What are your supervisors doing? You are supposed to go to the hospital every time you are shocked and stay over night, because your heart could stop beating (even with low voltages). To be honest, who does it?! But yeah... no apprentice should be shocked multiple times in training...
James Nguyen Or wear a metal suit of armor with a thick rubber lining on the inside. Electricity is lazy, after all: it takes the easiest path possible.
One part about the muscle contractions is that if you hold a object in your hand and you get shocked from it you will grip it harder. In other words if you grab something that hold a current you might not be able to let go of it. This was one of the first warnings I got from my education as an electrician and while you should never fiddle around with electricity unless you are absolute sure what you are doing, it might be good to have in the back of your head. In other words just one more reason to not touching exposed cables and similar things.
I was electrified once, when I was a kid (maybe in my early teens or tween years?). I was unplugging one of those little plug-in air fresheners, and as I did, my finger slipped and touched the metal prongs while they were still halfway inside the outlet. My hand cramped/contracted painfully and it felt like the entire thing was vibrating in the two seconds before I dropped it. Another time, I wanted to see if the general advice to not stick things in an outlet was realistic. (I was a curious, yet risky, child.) So I stuck metal tweezers into one, with both arms of the tweezers in different outlet holes. Of course, this completed the circuit... I didn't get electrified (luckily!), but there was a huge spark and a loud "CRACK!" and I jumped out of my skin. The outlet... was ruined. I never told my mom what happened, but a few days later she tried to plug something in and was like, "Why isn't this working?" I just shrugged. Long story short: I am a curious person and I was a risky child and I love electricity.
Yea - as a much younger man I was asked to check/replace a fuse on my friends hi-fi amp. He hands it to me, I take off the cover grab the fuse...and ZAP. He forgot to take out the power cord and i assumed he had taken it out (i was sitting cross-legged on his bed and he put the amp in my lap). This was hooked to a 240V outlet in Europe btw.
None of this would have happened if US plugs/sockets weren't so unsafe. In Europe there's shutters on the plug socket to stop anything being inserted and the pins are partially insulated so you can't touch the metal parts while they are live. It's much safer that way.
Got shocked in a wet bathroom once. I was unplugging some electric stuff and my arm just jolted as the lights went out. Arm was paraliyzed for a few minutes and got ok eventually. Then casually bathed in the dark while everyone else in my family wondered why the breaker suddenly operated. This experience made me respect electricians&electrictity in general.
When I was little and my grandparents were moving, they didn't have the covers on the new light switches yet. I tried to turn on a light in the dark and stuck my finger in the open socket instead. It didn't hurt me but it made me scream and cry.
By "didn't hurt me", I mean I wasn't injured. But as a child who just experienced an electric shock knowing how dangerous it is, it was a terrifying experience
When was the first usage of that cartoonic skeleton-flashing-through-the-skin thing? It's a really weird idea, and I wonder what went through the animator's head when they drew it like that.
Try turning on an old school filament light bulb? That is what the effect is in cartoons - A human being turned into a light bulb because they have power running through them.
RealLuckless That's probably true, but with very high powered electrocutions you might just see a skeleton. My grandfather worked around high-power lines and said that he once saw a bird land on one, which doesn't complete a circuit, but then it pecked something else electrical. There was just a poof of feathers and no more bird.
When I was in elementary school the water fountain shocked me so hard I lost vision for a moment and fell on my ass. As much as I tried with other students I could not get it to shock again, I still have no idea what the hell that was about.
My dad almost died because he cut what he thought was a dead circuit inside a fridge. Turns out it was still plugged in. What saved him was that he was crouched, and he fell back, breaking his locked grip on the wire snips. He remembered feeling the current passing up his arms and through his chest. One stupid mistake could have ended his life, he was just damn lucky.
I'm glad he mentioned that its not just the amount of current that contributes to a lethal shock, but also the amount of voltage and the resistance of your body. I've seen so many arguments about whether current or voltage is the killer - its BOTH! The just put "Danger High Voltage" warning signs on power sources because that's easily recognized by the average person. 500 volts is considered high voltage, but a static shock has anywhere between 25,000 and 50,000 volts... but practically no current! That's why it doesn't kill you; it doesn't have enough current and your body has hundreds of thousands of ohms of resistance on average! Well done, SciShow!
actually it does have a high amount of current, you can't just wave away ohm's law the point is that it's only there for such a short amount of time that it doesn't transfer any significant amounts of energy... it's the joules that kill you ;)
Exactly. Saying that the amps kill you and not the volts is like saying that it's not the bullet that kills you, it's the gun. You can't have one without the other.
I actually will stand corrected on that, I forgot that for mere nanoseconds, there is a massive current spike that can be from tens to a hundred or so amps. That said, we must also consider that the time of exposure to high current and voltage is a giant factor in injury / death by electric shock. Thanks, mate!
I like seeing these kinds of videos, especially as an electrician myself, and in school we were shown all types of ways that electricity can mess you up. I'd be really interested to see why specifically Arc Flashes happen too, because we were really grilled on those because those will just vaporize a man. Moreso on how it happens, whether it's just charge building up and the medium overloading or what. Could be interesting.
As far as I understand them, arc flashes happen when the high voltage ionizes the air, and basically turns air into a conductor. Anything is a conductor with high enough voltage. It makes a big ass fireball and can fling molten metal around, bad news.
I recently had TENS (transcutanious electrical nerve stimulation)for back pain. The application was painful but I was in a lot less pain for the next 48 hours, it felt like the ultimate deep tissue massage! Apparently in ancient Greece and Rome they used electric eels and rays to treat chronic pain, and I can see why.
The path of the current is important. The risk grows when the path crosses the heart, the spinal column, or the brain. However, you can't count on high skin resistance and/or a peripheral current path as a protection. A sustained current, such as between 2 fingers on the same hand can often increase, exponentially, likely due to electrolysis in cells arranging a preferred current path and (salty) perspiration forming at the point of skin contact. So even at 125V, it can go from tingle, to pain, to burns with time. :o
Karabetter I accidentally grabbed both sides of a live, exposed 120 volt outlet once with thumb and index finger, and that's the path it took. I felt throbbing as the waves of AC current went through and was able to let go after a moment which felt much longer. It hurt some, but was more numbing than anything.
Most of the time with 115-125V, luckily that is all that will happen. My uncle was not lucky and also being slightly careless. He had a tight hold on an electrical outlet and was using it as a handle to pull the copper wires it was attached to out of what he thought was a continuous conduit run. Of course the wires were disconnected, but he had left the other ends exposed. Well they actually passed through a junction box hidden in a wall that had a second live circuit. They managed to get energized and with his tight grip, his muscles clamped down and he could not let go. He was smart enough not to get his other hand involved. My dad quickly cut the wires. Couldn't have been more than a minute, but he did get 2 fingers burned, one blistered. The difference was probably the pressure of his grip. Similar to how you can change the resistance reading on an ohmmeter depending how hard you squeeze the probes. ;)
Karabetter That’s why you’re supposed to brush a live wire away with the back of your hand, rather than grab it: you hand will contract AWAY from the wire
It would have been cool if you talked about the differences with AC and DC when getting an electric shock. And the different symptoms one could develop.
Kickyour Definitely. This video seems to be working off DC assumptions, though a longer video with a full breakdown on AC/DC shocks, lightning strikes, and such would be interesting.
Kickyour Not really. Both alternating current and direct current are equally dangerous, as both were used for executions. Alternating current can(arguably) have more ways to enter your body, but if the voltage of either is high enough both will kill you. The idea that either one was more dangerous began as a scientific debate where people wanted money to power a city, so there’s also that.
The thing about AC is the fact that it forces the heart to contract 100/120 times per second (EU/US). If you were shocked for a little longer, even half a second is long enough, it is advised to go to the hospital and put yourself on an ECG to check if your heart is still working properly. Most deaths occur way after the incident due to heart failure.
Not only that, but with AC, everything has a capacitance that increases the in-rush current and the human body has a natural inductance that sustains the increased current. In addition, the (relatively) low 50/60Hz frequency also leads to a increased skin depth, leading to the overall decrease of effective resistance.
I’m an electrician and If I close my eyes and think about the times I’ve been shocked I can still feel it going up my arm through my chest.. I hate that my boss asked us to work with the power on just to convenience our customers..
Agreed. Back in my early days I did a lot of mall store building/maintenance and was changing 277/480 fixtures live all the time during business hours. Really glad I don't do that anymore, even a partial hit is enough to make you rethink life choices.
Well I remember a time when I didnt know I was in for a slight shock. I was unplugging my laptop from an outlet at home that had exposed frayed wires. When I went to grab the charging cable my hand slipped and I touched the wires instead. I felt my left arm seize up a bit and felt the current run through me as the edges of my vision faded slightly.
Once I gave myself a pretty good shock when I tried unplugging something with my fingers too close to the prongs. My whole arm hurt but I was really energetic shortly after.
my worst one was from one of those electroshock therapy machines. i asked the lady if a stronger shock is better and she said yes so i kept slowly increasing the voltage over the hour of treatment i had to go through. i increased it one step, took some time to get used to the pain until i was able to increase it further. the shock i felt was unbearably painful at the start was like a third of the strength of the shock i was taking at the end. it was a 1hz on-off sine modulation on a 120hz dunno-the-voltage ac shock. shouldn't have done that though. my hand was numb and "Pulsating" for a whole day after the session. but i maxed out the machine!
It's amazing how much detail you put into your research. The defibrillator stood out to me especially as most people have an ENTIRELY wrong picture of what it does. It's NOT used if your heart is standing still, that's what CPR is for. It is ONLY SPECIFICALLY used in very irregular heartbeats called "pulse-less ventricular tachycardia" which would look like an extreme zig-zag line in an EKG. Heart muscles contract irregularly and don't allow for a rhythmic contraction to pump blood through your body. As you guys correctly described it, the defibrillator resets these irregular contractions. Just love the amount of detail in these episodes.
Finally! Electrocution explained. I have been on that stump trying to educate people on the definition of electrocution. Yes, a High Voltage shock is very traumatic, if you survive. I was shocked be 13,ooo volts while working. It entered my right palm and exited my left heel. Life altering damage ensued! But I was not electrocuted.
1: the heart can stop with only 30mA, not 100. 2: It all depends on where the current flows, foot to foot isn't nearly as dangerous as hand to foot 3: the barrier for high voltage is 1000V for ac and 1500V for DC
Thank you! I was looking for this comment. I agree with you(and so does the field of science) except for point 2. There are still uncertainty on whether or not the current actually need pass through the heart or not. A lot of observation and studies show that nerve and muscle fabrics can be damaged outside of the theorized path of the current. Technically speaking the path of least resistant can be longer of the conducting capacity of the longer path is better. That in term may lead the current past it's exit point and back, if that is where the resistants is lowest. This video appears to incorrect or misleading. It may be that it's based on US research. If you want more up to date facts you should look into European research and especially Norwegian of Danish. Friendly advice for an electrician and health and safety rep.
Had a thief attempt to take copper at a closing power plant. He thought it would be a good idea to take bolt cutters to 40,000 volt line, that he ignored the humming. It cooked him from the inside out and took thee days to die.
Something similar happened in my town. Some dude was trying to strip down an abandoned house, guess he thought the power had been shut off to the home, but nope. Not only did he die, but the house burned down as well from a fire that started from him. This was right across the street from where I worked at the time.
1:15 THIS IS WRONG. You don't get electric burns because " nerves and muscles get over stimulated" its simply because with higher voltages, the high resistance of you body tissues means it heats up.
I got shocked before by a live wire. I've worked construction with my dad since I can't remember when. We were putting the finishing touches on our garage we had just finished renovating. After the paint had set it was time to put the plates back on the outlets and light switches. As our luck had it one of the plates broke while screwing it back into place. A few days later without a new plate on the light switches and the garage being as dark as it was I couldn't see the switches. Walking around barefoot while feeling around the wall for it my fingers slipped between the two switches where I learned what electricity felt like. It was such a shocking experience! I never felt more alive in my life! My heart felt like it was about to jump out of my chest and I left a rushing/tingling feeling throughout my entire body. I felt as if my very soul had been electrified. I saw swirling lights in the dark room and felt really light headed. It was almost like I was high or something. I felt numb but at the same time I felt everything. My mind was blank, but I felt peaceful. It was probably one of the scariest things in my life, but also one of the coolest.
There are people who call electric shocks electrocutions? Lol. I've never heard anyone say that.. You would think the "-cution" would be a "dead" giveaway lol.. Zing! ..I kill me..
Electrocution is death caused by electric shock, electric current passing through the body. The word is derived from "electro" and "execution", *but it is also used for accidental death.* *The word is also used to describe non-fatal injuries due to electricity.* true story
Being electrocuted actually saved my life, twice. First when I was going into cardiac arrest and defibrillated. Second I now have an internal defibrillator that saved me when I went into V-fib ( I was shocked like 18 times). It is very painful, I do not recommend it.
Probably because the title is 'what happens when you get electrocuted" and then starts "when you get shocked"... People get pretty butthurt that people commonly use electrocuted to mean shocked. Some people just don't want to accept that words change in meaning over time.
One other thing is the type of current matters a lot too. If the current is DC then it is relatively non fatal since you would drop whatever is shocking you pretty quickly. But if the current is AC, the flow of charge keeps alternating at a frequency which causes your muscles to uncontrollably spasm meaning you would grip on to whatever is shocking you.
All out savage depends what type of electrocution. There are different types. I’m not an electrician but I can think of 3 different kinds that have different affects.
@@KingdaToro I was electrocuted by 14,400 volt high line. Had to be resuscitated twice on the way to the hospital. Both my feet are completely skin grafted and I ended losing three toes on one foot and they were somehow able to save my other foot completely after telling me I’d have to have it amputated from the shin down
I can tell you without watching this video. I almost died from being electrocuted...we moved a lot, and I was 9yo grew up in Australia for a few years. We had 240v Electricity. My stepdad was a wannabe electrician. He Warned us kids not to touch these electric wires that were powerful enough to kill cats. He installed them on our bird Avairy. Long story short, I was stuck on the wires, my hands clenched shut on the wires, I couldn’t move, couldn’t yell out. The sound of being electrocuted deafens with intense buzzing. I couldn’t do a damn thing, but think over the loud noise of a way to get off the wires. I tried and tried and tried. I was finally able to get one hand off but it violently latched onto my other arm. Then I woke up on the ground. I didn’t know how I wasn’t on the wires anymore, I didn’t know why I was on the ground. I could not get up. It felt like I didn’t have any muscles anymore. I felt extremely nauseous. I just laid there and passed out again. I woke up again and tried to get up, I still couldn’t. I don’t know how long I was electrocuted for, I don’t know how long I was passed out for. I stayed laying there until I felt like I could get up. I was able to get up on all 4’s, very wobbly though. I’m tried to stand but couldn’t. So I laid back down. Eventually I could, made my way to the house a 1/4 acre away, had to keep stopping to lay down. I made it to the door, crawled in and my grandmother started by saying “Where have you...” she looked at me and gasped, and said “What happened to you?” I said I’d been electrocuted. She said I had no color anywhere at all. I went to my bedroom and laid down.I heard my grandmother yell to my mom that I was electrocuted. My mother yells out to my stepdad that I was electrocuted. Some time went by and my stepdad came into my room, sat on my bed ( he never did that before) and said I was extremely lucky to be alive. I told him I didn’t feel lucky at all. He asked me how I broke the wire. I said I didn’t. I didn’t know the wire was broke. He said I must have been stuck on the wire a long time, because the electrical panel caught fire. The electrical panel that caught fire was older than me at the time, it looked like it was from the 1950’ or earlier. I was out of commission for about 2 weeks. As I got older i Learned a bit more. I found out, that if you go unconscious or die while being electrocuted, you still get electrocuted because the connection isn’t severed. So, the last thing I remember was getting the one hand off the wire and it thrust onto my other arm. So, how did I end up on the ground? How did the wire break? That’s what I tried to figure out. Technically, the type of electrical panel had no safety features, so I should have been stuck there forever until the electrical connection was severed. What I had initially forgot was, my stepdad told me that the electrical panel caught fire. I talked with an electrician about it, he was more concerned with my stepdads wiring technique lol But he told me that the reason I was able to get a hand off the wire was when the electrical panel sparked, then reconnected. The most likely explanation for me being on the ground and why the wire was broken, he explained that after the spark at the panel, it eventually caught fire, severing the connection. He said I was mostly likely unconscious while being electrocuted, when the connection was severed from the fire, I dropped to the ground. He said in theory I should be dead. He said he wouldn’t be surprised if what my stepdad did was illegal at the time. To this day, I hate electricity. But I have no choice to use it. I’m pretty sure I have ptsd from it. I wish it happened just like a movie portrays an electrocution.
im a little bothered by this video. i was an electrician and it seemed hank was infering household current couldnt kill you because its not high voltage, but that isnt true, i know/knew people who have died from household current in extremely bizzare circumstances. one man was in his swimming pool draining it with sump pump and the pump fell into the pool. obviously it wasnt plugged into a gfi. just be careful and wise when working on electrical, when in doubt, consult an electrician, or at least google it, there are quite a few sites/blogs that can guide you through simple fixes. better safe and wise than cold n dead. and yes the title of vid didnt really match by explaining the multitude of effects when you light yourself up.
love scishow and all its different affiliated shows, so cool u rule. and hank humor is the bomb, thats how i got hooked! keep up the awesome work gang.
I had an issue with an old ungrounded fridge with a faulty wire. When I grabbed the metal handle to open the door, the current going though my arm made it difficult to let go. I stepped away to free my hand. It wasn't hot or painful so I imagine there wasn't much voltage getting to the handle and myself, thankfully. I trashed the fridge the following day.
Got electrocuted at work the other day. I was fixing a drilling rig and testing the progress along the way. Between one of the tests, I unplugged the wrong cable and the next time I was working with the unmounted switch, my middle and index fingers came in contact with the live and neutral terminals of the switch. I felt no pain or burning as the current flowed up one finger and down the other to complete the circuit. Only felt a mild vibration as 120V pushed a small current through my fingers. Definitely shook me good. Will be a lot more careful going forward. 👌🏾
You missed one important bit where you won't feel a thing if you aren't touching "ground". Meaning you could touch any live wire of virtually any voltage and not feel a thing if you are jumping in the air. It is only when you touch the ground does the current pass through you.
Shem Doupe You don't have to be touching ground, you just have to provide a path from high potential to low potential. If you grab 2 bus bars of a 3 phase circuit, you will create that path from one arm, through your heart and out the other arm, regardless if you are touching ground or not.
Yes and no. Air is not inherently conductive, but given a high enough charge air can become ionized and thus function exactly as a conductor. Which is how lightning strikes work.
Voltage and your own resistance aren't the only two important factors determining the current that flows through you... it is also very important to consider the way you close the circuit. if you were to touch a single live wire, you would be making a ground fault, which adds the resistance of the ground to the equation, drastically lessening the current. However, if you were to touch both the live wire and the neutral wire at the same time, you would be closing the circuit through you only, and be expossed to a much higher current. There are some other things to consider like protection pick up currents and reaction time, and also short circuit level at the location of the fault.
I got shocked by 277, I touched a single brown wire and it got me for a good second, I let go but everything in my body was vibrating, felt disoriented for a while but now I’m okay, I LEARNED MY LESSON, ALWAYS TEST THE WIRE!
I'm an electrician and I had an accident two years ago, every time I try to remember this moment I "feel" this strange and strong pain again. Can't recommend, had to go to the hospital and was on 24h watch for my heart. Thankfully nothing long lasting happened.
A very simplistic explanation to electrocution. 500 volts can only kill you provided that it carries enough current. I’ve got videos on TH-cam shocking myself with 45,000 volts but the current is only 2ma rendering no damage.
Everything up to 2:39 is correct. After that there are some technical inaccuracies. Such as 500 volts is technically low voltage. Also anything above 50 volts (30 volts if you do the math) can be hazardous.
Anything having more than .1amp of charge is capable of stoping your heart if it makes a complete circuit. 120V or 220V outlets have about 20A in them therefore if its a complete circuit it may stop your heart and cause death.
I appreciate your comment because it addresses an issue that I find with the video. He makes it seem like household voltages aren't a high enough voltage to be shocked by or at least that they aren't dangerous. That's not true, 120 vrms at .1 A or more is totally dangerous if it goes through your chest. Technically at my work when we work with more than 50v we already start to take extra precautions with added precautions as voltage increases.
Yea I'm an Electrician's mate in the US Navy, we work with systems up to 450V AC on my ship, which is considered well above the high voltage. Him saying that anything above 500V is high voltage is simply not true, the high voltage mark is well below that.
JokerPoker5RP I think the term hank is using equates to what can damage the tissue, not just electrically cause muscle misfire... I also am an electrician, and anything above 50 volts is termed high voltage to my field... scientists must use different terminology. Because, 120-230v shocks, are SIGNIFICANTLY less destructive than 480v and up... still deadly... but less destructive to the body.
JokerPoker5RP I got electrocuted as a child 2 times, the sensation is strange and you can feel all your nervous system pulsating trying to rehabilitate. Kids, don't stick your fingers into power outlets even if it is tempting.
Voltage potential is analogous to gravity potential. Having the water higher up in the pipe would cause it to want to flow more. What you described with the pipe being restricted is analogous to resistance. Having a larger wire has less resistance and current can flow more easily. Fun fact that may make for a good episode: Electricity, fluid flow, and heat transfer all use the same math and physics to model their behavior.
You forgot to explain AC and electrocution. AC alternates current. AC in the US run at about 60 Hz, which is about inline with the rhythm of the average human heart. Meaning your heart is more likely to stop being shocked by AC than DC.
I may be wrong, but as I recall direct current locks your muscles, making it impossible to let go and alternating current does not have that effect. Therefore, AC current is safer, and that was part of the argument that got it to be the standard in the US. You don't want to grab a live wire either way though.
2:05 is saying "making it harder for the water to flow" really the correct way to explain flow here? Would it not be better to say that the voltage is like water pressure (as you said) and resistance would be like a reduction in pressure such as narrowing of the pipe? As at the narrow section, the speed increases but the pressure decreases, in accordance with Bernoulli (please correct me if I'm wrong or have misunderstood) Ofc I think it's better not to include talk of speed and Bernoulli at this stage, but using the word harder instead of pressure could cause the wrong assumptions in future, what do you think about this?
This is oddly timed to when I got an electric shock at work. The water heater in the aquarium system short circuited and we could only test for it by sticking our hands in the water. We turned the system OFF and my coworker got the worst of it and got shocked directly rather than through the water when she unplugged the heater that short-circuited. Had one hell of a headache the rest of the night and random muscle twitches all over.
One time when I was younger I stuck a bobby pin in a light socket at the hairdressers. I have no memory of this day, but I was told the power went out and my fingers turned black lol
here because as a new electrician, i learned it's extremely common to shock yourself on the job. like almost every day. but a 120v shock from any residential receptacle or light fixture feels at worst like those shock pens your uncle tricks you with. but a toaster in a bathtub from the same 120v circuit is certain death.
I scored a really long lead with a light socket on the end once. Utilised the hell out of it. Light wherever I wanted. Bear in mind this was back in the early 90s...but anyway. I had it plugged in with no bulb and my curious mind wondered what it would be like to get shocked. Perfect opportunity to find out. I had a plan, quickly tap the prongs with my finger tip and out again. Successful experiment. I felt a bit of a jolt, and a high frequency vibration, much like when you touch something vibrating at high frequency it hurts. That's what felt like, I don't know for sure if any vibration took place. A burn mark from one of the prongs topped it off.
wth it took a whole month before youtube suggested this video to me... I been binge watching this channel. Just seems like this is the type of info that could be considered to be very pertinent in every day life. *slow clap for youtube algo*
I used to learn about electronics by messing with them and sometimes I got a little buzz and tingles on my hands. Now that I learned an electrocution isn't as flashy and it doesn't take much to stop a heart, I know it wasn't just a weird feeling but the things were actually zapping me. I am kinda scared to keep on with my "practical research" now
The accepted boundary between safe voltages and higher voltages in electrical equipment is 42 V not 120 V as stated. Safety standards dictate increased insulation and physical protection from contact above 42V.
"In a healthy person, stopping the heart is obviously very, very bad." Learn something new every day
I'm an apprentice electrician and have been shocked a good amount of times already. Thanks for clearing up why I'm not dying!

You are supposed to go to the hospital every time you are shocked and stay over night, because your heart could stop beating (even with low voltages). To be honest, who does it?! But yeah... no apprentice should be shocked multiple times in training...

If you're able to make lightning hit you and have a high enough internal resistance to keep it from entering your body.
If you are lucky the lightning stops your heart and paramedics are able to resuscitate your heart before you are dead for good

One part about the muscle contractions is that if you hold a object in your hand and you get shocked from it you will grip it harder. In other words if you grab something that hold a current you might not be able to let go of it.
This was one of the first warnings I got from my education as an electrician and while you should never fiddle around with electricity unless you are absolute sure what you are doing, it might be good to have in the back of your head.

I was electrified once, when I was a kid (maybe in my early teens or tween years?). I was unplugging one of those little plug-in air fresheners, and as I did, my finger slipped and touched the metal prongs while they were still halfway inside the outlet. My hand cramped/contracted painfully and it felt like the entire thing was vibrating in the two seconds before I dropped it.
Another time, I wanted to see if the general advice to not stick things in an outlet was realistic. (I was a curious, yet risky, child.) So I stuck metal tweezers into one, with both arms of the tweezers in different outlet holes. Of course, this completed the circuit... I didn't get electrified (luckily!), but there was a huge spark and a loud "CRACK!" and I jumped out of my skin. The outlet... was ruined. I never told my mom what happened, but a few days later she tried to plug something in and was like, "Why isn't this working?" I just shrugged.
Long story short: I am a curious person and I was a risky child and I love electricity.
Yea - as a much younger man I was asked to check/replace a fuse on my friends hi-fi amp. He hands it to me, I take off the cover grab the fuse...and ZAP. He forgot to take out the power cord and i assumed he had taken it out (i was sitting cross-legged on his bed and he put the amp in my lap). This was hooked to a 240V outlet in Europe btw.
I stuck a toothpick in an outlet lol. All that happened was red sparks flew out and I burned my finger a bit. It was pretty cool looking
And i thought i was the only one...
But, did you die?
None of this would have happened if US plugs/sockets weren't so unsafe. In Europe there's shutters on the plug socket to stop anything being inserted and the pins are partially insulated so you can't touch the metal parts while they are live. It's much safer that way.
Wow that pipe analogy is absolutely beautiful
David Schartung yeah, taking a hydraulics class BEFORE my class on electric circuits was super helpful lol
Yes indeed now its not difficult for me to differentiate voltage and current hehe which was a bit of a problem
no matter how many videos i watch explaining how electricity works, it's still basically magic to me.
but im still fascinated by electricity.
Got shocked in a wet bathroom once. I was unplugging some electric stuff and my arm just jolted as the lights went out. Arm was paraliyzed for a few minutes and got ok eventually.
Then casually bathed in the dark while everyone else in my family wondered why the breaker suddenly operated. This experience made me respect electricians&electrictity in general.
Why did I get an ad to switch my electricity provider lol
AustriaTV - because your current electricity provider will electrocute you maybe?
No puns intended with the word "current" by the way
They’re warning you
Hahaha
Short Answer: You die.
Long Answer: *this video*
When I was little and my grandparents were moving, they didn't have the covers on the new light switches yet. I tried to turn on a light in the dark and stuck my finger in the open socket instead. It didn't hurt me but it made me scream and cry.
By "didn't hurt me", I mean I wasn't injured. But as a child who just experienced an electric shock knowing how dangerous it is, it was a terrifying experience
When was the first usage of that cartoonic skeleton-flashing-through-the-skin thing? It's a really weird idea, and I wonder what went through the animator's head when they drew it like that.
Try turning on an old school filament light bulb? That is what the effect is in cartoons - A human being turned into a light bulb because they have power running through them.
RealLuckless
That's probably true, but with very high powered electrocutions you might just see a skeleton. My grandfather worked around high-power lines and said that he once saw a bird land on one, which doesn't complete a circuit, but then it pecked something else electrical. There was just a poof of feathers and no more bird.
@@lordelliott42 You may just become a skeleton if they are electrocuted
When I was in elementary school the water fountain shocked me so hard I lost vision for a moment and fell on my ass. As much as I tried with other students I could not get it to shock again, I still have no idea what the hell that was about.
I think you'll find the answer shoc... nvm.
My dad almost died because he cut what he thought was a dead circuit inside a fridge. Turns out it was still plugged in. What saved him was that he was crouched, and he fell back, breaking his locked grip on the wire snips. He remembered feeling the current passing up his arms and through his chest. One stupid mistake could have ended his life, he was just damn lucky.
I'm glad he mentioned that its not just the amount of current that contributes to a lethal shock, but also the amount of voltage and the resistance of your body. I've seen so many arguments about whether current or voltage is the killer - its BOTH! The just put "Danger High Voltage" warning signs on power sources because that's easily recognized by the average person.
500 volts is considered high voltage, but a static shock has anywhere between 25,000 and 50,000 volts... but practically no current! That's why it doesn't kill you; it doesn't have enough current and your body has hundreds of thousands of ohms of resistance on average! Well done, SciShow!
You are correct. This is much the same as people saying it is not the HP but the Torque of an engine that matters.
actually it does have a high amount of current, you can't just wave away ohm's law
the point is that it's only there for such a short amount of time that it doesn't transfer any significant amounts of energy... it's the joules that kill you ;)
Exactly. Saying that the amps kill you and not the volts is like saying that it's not the bullet that kills you, it's the gun. You can't have one without the other.
I actually will stand corrected on that, I forgot that for mere nanoseconds, there is a massive current spike that can be from tens to a hundred or so amps. That said, we must also consider that the time of exposure to high current and voltage is a giant factor in injury / death by electric shock. Thanks, mate!
Vittaminn Also if the voltage is to high, there is no way for the current to be low enough to save you
Came here after watching the 8 year old boy who got electrocuted back in 2022 and pulled by the officers. Very sad video :(
I think I am tramatizes by the gurgles of the boy choking on his own spit and the blood curtaling screams of the wittness
"Death by electric shock"
Me: oh that explains a lot
My name is Barry Allen, and I'm the fastest man alive...

Aren't you supposed to be in the jail?
I like seeing these kinds of videos, especially as an electrician myself, and in school we were shown all types of ways that electricity can mess you up. I'd be really interested to see why specifically Arc Flashes happen too, because we were really grilled on those because those will just vaporize a man. Moreso on how it happens, whether it's just charge building up and the medium overloading or what. Could be interesting.
As far as I understand them, arc flashes happen when the high voltage ionizes the air, and basically turns air into a conductor. Anything is a conductor with high enough voltage. It makes a big ass fireball and can fling molten metal around, bad news.
Yeah, an ex was a lineman and omg... Arcs and fireballs are horrific!
I recently had TENS (transcutanious electrical nerve stimulation)for back pain. The application was painful but I was in a lot less pain for the next 48 hours, it felt like the ultimate deep tissue massage! Apparently in ancient Greece and Rome they used electric eels and rays to treat chronic pain, and I can see why.
The path of the current is important. The risk grows when the path crosses the heart, the spinal column, or the brain.
However, you can't count on high skin resistance and/or a peripheral current path as a protection. A sustained current, such as between 2 fingers on the same hand can often increase, exponentially, likely due to electrolysis in cells arranging a preferred current path and (salty) perspiration forming at the point of skin contact. So even at 125V, it can go from tingle, to pain, to burns with time. :o
Karabetter
I accidentally grabbed both sides of a live, exposed 120 volt outlet once with thumb and index finger, and that's the path it took. I felt throbbing as the waves of AC current went through and was able to let go after a moment which felt much longer. It hurt some, but was more numbing than anything.
Most of the time with 115-125V, luckily that is all that will happen.
My uncle was not lucky and also being slightly careless. He had a tight hold on an electrical outlet and was using it as a handle to pull the copper wires it was attached to out of what he thought was a continuous conduit run. Of course the wires were disconnected, but he had left the other ends exposed. Well they actually passed through a junction box hidden in a wall that had a second live circuit. They managed to get energized and with his tight grip, his muscles clamped down and he could not let go. He was smart enough not to get his other hand involved. My dad quickly cut the wires. Couldn't have been more than a minute, but he did get 2 fingers burned, one blistered.
The difference was probably the pressure of his grip. Similar to how you can change the resistance reading on an ohmmeter depending how hard you squeeze the probes. ;)
Karabetter
That’s why you’re supposed to brush a live wire away with the back of your hand, rather than grab it: you hand will contract AWAY from the wire
It would have been cool if you talked about the differences with AC and DC when getting an electric shock. And the different symptoms one could develop.
277v shock was an awful experience! You can never forget something like that.
You forgot to mention ac/DC that also makes a difference.
Kickyour Definitely. This video seems to be working off DC assumptions, though a longer video with a full breakdown on AC/DC shocks, lightning strikes, and such would be interesting.
Kickyour Not really. Both alternating current and direct current are equally dangerous, as both were used for executions. Alternating current can(arguably) have more ways to enter your body, but if the voltage of either is high enough both will kill you. The idea that either one was more dangerous began as a scientific debate where people wanted money to power a city, so there’s also that.
The thing about AC is the fact that it forces the heart to contract 100/120 times per second (EU/US). If you were shocked for a little longer, even half a second is long enough, it is advised to go to the hospital and put yourself on an ECG to check if your heart is still working properly. Most deaths occur way after the incident due to heart failure.
AC is more dangerous because of the frequency of the current. AC with 50 hz frequency will make your heart beat 100 times per second.
Not only that, but with AC, everything has a capacitance that increases the in-rush current and the human body has a natural inductance that sustains the increased current. In addition, the (relatively) low 50/60Hz frequency also leads to a increased skin depth, leading to the overall decrease of effective resistance.
I can easily say that this video was very electrifying.
I’m an electrician and If I close my eyes and think about the times I’ve been shocked I can still feel it going up my arm through my chest.. I hate that my boss asked us to work with the power on just to convenience our customers..
Agreed. Back in my early days I did a lot of mall store building/maintenance and was changing 277/480 fixtures live all the time during business hours. Really glad I don't do that anymore, even a partial hit is enough to make you rethink life choices.
Well I remember a time when I didnt know I was in for a slight shock. I was unplugging my laptop from an outlet at home that had exposed frayed wires. When I went to grab the charging cable my hand slipped and I touched the wires instead. I felt my left arm seize up a bit and felt the current run through me as the edges of my vision faded slightly.
Once I gave myself a pretty good shock when I tried unplugging something with my fingers too close to the prongs. My whole arm hurt but I was really energetic shortly after.
Muscle Hank, where you at ?
When my sister tries to stick a fork in the outlet:
*WHEN WILL YOU LEARN*
*WHEN WILL YOU LEARN*

The worst shock I’ve every gotten was when I was plugging in a plug and it shocked me and couldn’t feel my hand for around 10 mins after thatz
reddit.com/r/thathappened
No wonder why your hand now types that extra 'z' at the end of words.
my worst one was from one of those electroshock therapy machines. i asked the lady if a stronger shock is better and she said yes so i kept slowly increasing the voltage over the hour of treatment i had to go through. i increased it one step, took some time to get used to the pain until i was able to increase it further. the shock i felt was unbearably painful at the start was like a third of the strength of the shock i was taking at the end. it was a 1hz on-off sine modulation on a 120hz dunno-the-voltage ac shock.
shouldn't have done that though. my hand was numb and "Pulsating" for a whole day after the session. but i maxed out the machine!
if you are american i 120 volt most European country's use 230 volts. plus it's the amps that's kills you not the voltage.
It's amazing how much detail you put into your research.
The defibrillator stood out to me especially as most people have an ENTIRELY wrong picture of what it does. It's NOT used if your heart is standing still, that's what CPR is for. It is ONLY SPECIFICALLY used in very irregular heartbeats called "pulse-less ventricular tachycardia" which would look like an extreme zig-zag line in an EKG. Heart muscles contract irregularly and don't allow for a rhythmic contraction to pump blood through your body. As you guys correctly described it, the defibrillator resets these irregular contractions.
Just love the amount of detail in these episodes.
i JUST got electric shock when i went to plug something into the wall.
Yeah and it made my finger bleed idk why so I was like why not search if it had some bad side effects 👀
My finger got electric shocked it didn’t bleed but it hurt for one second
Why are yall making it look like a huge deal, if your muscles werent contracted in a way that you cant let go, it doesnt matter
Finally! Electrocution explained. I have been on that stump trying to educate people on the definition of electrocution. Yes, a High Voltage shock is very traumatic, if you survive. I was shocked be 13,ooo volts while working. It entered my right palm and exited my left heel. Life altering damage ensued! But I was not electrocuted.
1: the heart can stop with only 30mA, not 100.
2: It all depends on where the current flows, foot to foot isn't nearly as dangerous as hand to foot
3: the barrier for high voltage is 1000V for ac and 1500V for DC
Thank you! I was looking for this comment. I agree with you(and so does the field of science) except for point 2.
There are still uncertainty on whether or not the current actually need pass through the heart or not. A lot of observation and studies show that nerve and muscle fabrics can be damaged outside of the theorized path of the current. Technically speaking the path of least resistant can be longer of the conducting capacity of the longer path is better. That in term may lead the current past it's exit point and back, if that is where the resistants is lowest.
This video appears to incorrect or misleading. It may be that it's based on US research. If you want more up to date facts you should look into European research and especially Norwegian of Danish.
Friendly advice for an electrician and health and safety rep.
Had a thief attempt to take copper at a closing power plant. He thought it would be a good idea to take bolt cutters to 40,000 volt line, that he ignored the humming. It cooked him from the inside out and took thee days to die.
That sounds painful.....
Cant feel bad for a thief
Something similar happened in my town. Some dude was trying to strip down an abandoned house, guess he thought the power had been shut off to the home, but nope. Not only did he die, but the house burned down as well from a fire that started from him. This was right across the street from where I worked at the time.
Flintstoned in the plant when he cut in, it left his footprints permanently in the tile
zack9912000 Well then.
1:15 THIS IS WRONG.
You don't get electric burns because " nerves and muscles get over stimulated"
its simply because with higher voltages, the high resistance of you body tissues means it heats up.
Well depending on how you read the statement, they could just be referring to seizures.
I think they meant for the burns to be separated from the contractions and seizures. However I can see why it looks confusing.
they address this later in the video, no worries!
but that's what he said
I got shocked before by a live wire. I've worked construction with my dad since I can't remember when. We were putting the finishing touches on our garage we had just finished renovating. After the paint had set it was time to put the plates back on the outlets and light switches. As our luck had it one of the plates broke while screwing it back into place.
A few days later without a new plate on the light switches and the garage being as dark as it was I couldn't see the switches. Walking around barefoot while feeling around the wall for it my fingers slipped between the two switches where I learned what electricity felt like.
It was such a shocking experience! I never felt more alive in my life! My heart felt like it was about to jump out of my chest and I left a rushing/tingling feeling throughout my entire body. I felt as if my very soul had been electrified. I saw swirling lights in the dark room and felt really light headed. It was almost like I was high or something. I felt numb but at the same time I felt everything. My mind was blank, but I felt peaceful. It was probably one of the scariest things in my life, but also one of the coolest.
I met a girl who was shockingly beautiful. My heart stopped when I saw her. She electro-CUTE-d me.
That must have been some hot sexy girl lol
I see

You're "conducting" a survey? It's a trap!
"Hopefully you won't ever expierience the true definition of electrocution"
Thats the nicest thing someone said to me this day 😂
This video is how to get electrocuted not what happens
@@theincarnationofboredom207 no it doesn't
it explained what happened, you are just bad at paying attention
This video dangerously understates the risks of household power supplies.
Something I'm constantly yelling at the TeeVee: "You don't shock a flatline!"
Thank you, Hank, for not saying, "Its the amps that kill" and taking all factors into consideration!
There are people who call electric shocks electrocutions? Lol. I've never heard anyone say that.. You would think the "-cution" would be a "dead" giveaway lol.. Zing! ..I kill me..
Electrocution is death caused by electric shock, electric current passing through the body. The word is derived from "electro" and "execution", *but it is also used for accidental death.*
*The word is also used to describe non-fatal injuries due to electricity.*
true story
Elocution is isn't death by pronunciation, so not a sure bet.
Don't get too amped up in your current state of zen 'er you'll impede your humorouses capacitanceiseses
;)
You'd think but I hear them used interchangeably a lot of the time.
I've heard people say they where electrocuted, I've probably said that at some point
I clicked this video to get information on what people feel when they get electrocuted, but it turns out this video tells me that shocks are dangerous
Being electrocuted actually saved my life, twice. First when I was going into cardiac arrest and defibrillated. Second I now have an internal defibrillator that saved me when I went into V-fib ( I was shocked like 18 times). It is very painful, I do not recommend it.
Ahh, the water pipe analogy. Gotta love electronic engineering!
Watching this makes me think of The Green Mile!
Ugh, that scene was so disturbing
THANK YOU FOR THAT INTRO DIFFERENTIATION. I hate trying to explain that electrocution means death. People never believe me. Even if I cite sources.
So, all this time I have been using the wrong word...
Shockingly enough,
you will get a firm and vivid
handshake from the Grim Reaper.
Someone already gave it a dislike even tho it’s been uploaded 20 seconds ago...
Haters gonna hate I guess
"It's science and disagree's with my Flat Earth model therefore I must dislike it."
Probably because the title is 'what happens when you get electrocuted" and then starts "when you get shocked"... People get pretty butthurt that people commonly use electrocuted to mean shocked. Some people just don't want to accept that words change in meaning over time.
maybe hank stole his wife.
Bots gonna bot.
20 seconds ago 2 years ago
One other thing is the type of current matters a lot too.
If the current is DC then it is relatively non fatal since you would drop whatever is shocking you pretty quickly.
But if the current is AC, the flow of charge keeps alternating at a frequency which causes your muscles to uncontrollably spasm meaning you would grip on to whatever is shocking you.
What Happens When You Get Electrocuted? You start praying... I know I did
Guess it worked
imagine getting struck by lightening and then suddenly not having heart problems anymore
Getting electrocuted is like getting stabbed but the knife goes trough your nerves I have felt it it hurts like hell
All out savage depends what type of electrocution. There are different types. I’m not an electrician but I can think of 3 different kinds that have different affects.
You've been shocked, not electrocuted. Nobody can correctly say they've been electrocuted, because if they have been, they're dead.
my arm just felt like jello touching a live PS1 PSU
I feel u, I literally just got electrocuted
@@KingdaToro I was electrocuted by 14,400 volt high line. Had to be resuscitated twice on the way to the hospital. Both my feet are completely skin grafted and I ended losing three toes on one foot and they were somehow able to save my other foot completely after telling me I’d have to have it amputated from the shin down
I can tell you without watching this video. I almost died from being electrocuted...we moved a lot, and I was 9yo grew up in Australia for a few years. We had 240v Electricity. My stepdad was a wannabe electrician. He Warned us kids not to touch these electric wires that were powerful enough to kill cats. He installed them on our bird Avairy. Long story short, I was stuck on the wires, my hands clenched shut on the wires, I couldn’t move, couldn’t yell out. The sound of being electrocuted deafens with intense buzzing. I couldn’t do a damn thing, but think over the loud noise of a way to get off the wires. I tried and tried and tried. I was finally able to get one hand off but it violently latched onto my other arm. Then I woke up on the ground. I didn’t know how I wasn’t on the wires anymore, I didn’t know why I was on the ground. I could not get up.
It felt like I didn’t have any muscles anymore. I felt extremely nauseous. I just laid there and passed out again. I woke up again and tried to get up, I still couldn’t. I don’t know how long I was electrocuted for, I don’t know how long I was passed out for. I stayed laying there until I felt like I could get up. I was able to get up on all 4’s, very wobbly though. I’m tried to stand but couldn’t. So I laid back down. Eventually I could, made my way to the house a 1/4 acre away, had to keep stopping to lay down.
I made it to the door, crawled in and my grandmother started by saying “Where have you...” she looked at me and gasped, and said “What happened to you?” I said I’d been electrocuted. She said I had no color anywhere at all. I went to my bedroom and laid down.I heard my grandmother yell to my mom that I was electrocuted. My mother yells out to my stepdad that I was electrocuted. Some time went by and my stepdad came into my room, sat on my bed ( he never did that before) and said I was extremely lucky to be alive. I told him I didn’t feel lucky at all. He asked me how I broke the wire. I said I didn’t. I didn’t know the wire was broke. He said I must have been stuck on the wire a long time, because the electrical panel caught fire. The electrical panel that caught fire was older than me at the time, it looked like it was from the 1950’ or earlier. I was out of commission for about 2 weeks.
As I got older i Learned a bit more. I found out, that if you go unconscious or die while being electrocuted, you still get electrocuted because the connection isn’t severed. So, the last thing I remember was getting the one hand off the wire and it thrust onto my other arm. So, how did I end up on the ground? How did the wire break? That’s what I tried to figure out. Technically, the type of electrical panel had no safety features, so I should have been stuck there forever until the electrical connection was severed.
What I had initially forgot was, my stepdad told me that the electrical panel caught fire.
I talked with an electrician about it, he was more concerned with my stepdads wiring technique lol But he told me that the reason I was able to get a hand off the wire was when the electrical panel sparked, then reconnected. The most likely explanation for me being on the ground and why the wire was broken, he explained that after the spark at the panel, it eventually caught fire, severing the connection. He said I was mostly likely unconscious while being electrocuted, when the connection was severed from the fire, I dropped to the ground. He said in theory I should be dead. He said he wouldn’t be surprised if what my stepdad did was illegal at the time.
To this day, I hate electricity. But I have no choice to use it. I’m pretty sure I have ptsd from it.
I wish it happened just like a movie portrays an electrocution.
im a little bothered by this video. i was an electrician and it seemed hank was infering household current couldnt kill you because its not high voltage, but that isnt true, i know/knew people who have died from household current in extremely bizzare circumstances. one man was in his swimming pool draining it with sump pump and the pump fell into the pool. obviously it wasnt plugged into a gfi. just be careful and wise when working on electrical, when in doubt, consult an electrician, or at least google it, there are quite a few sites/blogs that can guide you through simple fixes. better safe and wise than cold n dead. and yes the title of vid didnt really match by explaining the multitude of effects when you light yourself up.
love scishow and all its different affiliated shows, so cool u rule. and hank humor is the bomb, thats how i got hooked! keep up the awesome work gang.
legacysage ya all i know is he was dead when we arrived, and they said electrocution was cause no autopsy tho
could also be the pump fell between the guy and some copper tubing, putting the guy in between the current and ground.
Can we please get a Hank Green Playlist?!?! I like the other hosts.. But Hank, well, my brudda, I love when you are hosting!!!!
reset button 😂😂 i feel slow i need to reset my heart
That'd be like Windows 95. It might reboot.....it might not.
Noice 😅
I had an issue with an old ungrounded fridge with a faulty wire. When I grabbed the metal handle to open the door, the current going though my arm made it difficult to let go. I stepped away to free my hand. It wasn't hot or painful so I imagine there wasn't much voltage getting to the handle and myself, thankfully. I trashed the fridge the following day.
ElectoBoom did it best
Got electrocuted at work the other day. I was fixing a drilling rig and testing the progress along the way. Between one of the tests, I unplugged the wrong cable and the next time I was working with the unmounted switch, my middle and index fingers came in contact with the live and neutral terminals of the switch. I felt no pain or burning as the current flowed up one finger and down the other to complete the circuit. Only felt a mild vibration as 120V pushed a small current through my fingers. Definitely shook me good. Will be a lot more careful going forward. 👌🏾
Everyone licked a 9V battery.
Love the new intro, please keep it short like that
You missed one important bit where you won't feel a thing if you aren't touching "ground". Meaning you could touch any live wire of virtually any voltage and not feel a thing if you are jumping in the air. It is only when you touch the ground does the current pass through you.
Shem Doupe not any voltage, if its high enough you will get shocked anyway, air is also a conductor
Shem Doupe
You don't have to be touching ground, you just have to provide a path from high potential to low potential. If you grab 2 bus bars of a 3 phase circuit, you will create that path from one arm, through your heart and out the other arm, regardless if you are touching ground or not.
Air isn't a conductor otherwise you wouldn't need wires to run through your house to get electricity
Yes and no. Air is not inherently conductive, but given a high enough charge air can become ionized and thus function exactly as a conductor. Which is how lightning strikes work.
1,000,000 V / cm
Voltage and your own resistance aren't the only two important factors determining the current that flows through you... it is also very important to consider the way you close the circuit. if you were to touch a single live wire, you would be making a ground fault, which adds the resistance of the ground to the equation, drastically lessening the current. However, if you were to touch both the live wire and the neutral wire at the same time, you would be closing the circuit through you only, and be expossed to a much higher current. There are some other things to consider like protection pick up currents and reaction time, and also short circuit level at the location of the fault.
I got shocked by 277, I touched a single brown wire and it got me for a good second, I let go but everything in my body was vibrating, felt disoriented for a while but now I’m okay, I LEARNED MY LESSON, ALWAYS TEST THE WIRE!
10.000V at 200A should be enough to... reliably relieve you of your burdens!
10kV at 200A would be enough to make you into a pile of ash
You don't say?
I'm an electrician and I had an accident two years ago, every time I try to remember this moment I "feel" this strange and strong pain again. Can't recommend, had to go to the hospital and was on 24h watch for my heart. Thankfully nothing long lasting happened.
U get shocked
A very simplistic explanation to electrocution. 500 volts can only kill you provided that it carries enough current. I’ve got videos on TH-cam shocking myself with 45,000 volts but the current is only 2ma rendering no damage.
Darryl Learie i think this guy broke ohm's law... GET IN THE BACK
Bzzzzap!
Everything up to 2:39 is correct. After that there are some technical inaccuracies. Such as 500 volts is technically low voltage. Also anything above 50 volts (30 volts if you do the math) can be hazardous.
Anything having more than .1amp of charge is capable of stoping your heart if it makes a complete circuit. 120V or 220V outlets have about 20A in them therefore if its a complete circuit it may stop your heart and cause death.
I appreciate your comment because it addresses an issue that I find with the video. He makes it seem like household voltages aren't a high enough voltage to be shocked by or at least that they aren't dangerous. That's not true, 120 vrms at .1 A or more is totally dangerous if it goes through your chest.
Technically at my work when we work with more than 50v we already start to take extra precautions with added precautions as voltage increases.
My bad the . didn't typed in
Yea I'm an Electrician's mate in the US Navy, we work with systems up to 450V AC on my ship, which is considered well above the high voltage. Him saying that anything above 500V is high voltage is simply not true, the high voltage mark is well below that.
JokerPoker5RP I think the term hank is using equates to what can damage the tissue, not just electrically cause muscle misfire...
I also am an electrician, and anything above 50 volts is termed high voltage to my field... scientists must use different terminology.
Because, 120-230v shocks, are SIGNIFICANTLY less destructive than 480v and up... still deadly... but less destructive to the body.
JokerPoker5RP I got electrocuted as a child 2 times, the sensation is strange and you can feel all your nervous system pulsating trying to rehabilitate. Kids, don't stick your fingers into power outlets even if it is tempting.
Voltage potential is analogous to gravity potential. Having the water higher up in the pipe would cause it to want to flow more. What you described with the pipe being restricted is analogous to resistance. Having a larger wire has less resistance and current can flow more easily. Fun fact that may make for a good episode: Electricity, fluid flow, and heat transfer all use the same math and physics to model their behavior.
You forgot to explain AC and electrocution. AC alternates current. AC in the US run at about 60 Hz, which is about inline with the rhythm of the average human heart. Meaning your heart is more likely to stop being shocked by AC than DC.
mtktm Not only that but our bodies act like (really bad) capacitors, so when the frequency increases the resistance or reactance of our body drops.
If your heart beats at 60 hz you have bigger issues than electricity
Just go see Electroboom he knows about electrocution better than anyone
I may be wrong, but as I recall direct current locks your muscles, making it impossible to let go and alternating current does not have that effect. Therefore, AC current is safer, and that was part of the argument that got it to be the standard in the US. You don't want to grab a live wire either way though.
In that case Elliott, I recommend never marrying a fiery redhead. ;)
2:05 is saying "making it harder for the water to flow" really the correct way to explain flow here? Would it not be better to say that the voltage is like water pressure (as you said) and resistance would be like a reduction in pressure such as narrowing of the pipe? As at the narrow section, the speed increases but the pressure decreases, in accordance with Bernoulli (please correct me if I'm wrong or have misunderstood) Ofc I think it's better not to include talk of speed and Bernoulli at this stage, but using the word harder instead of pressure could cause the wrong assumptions in future, what do you think about this?
This is oddly timed to when I got an electric shock at work. The water heater in the aquarium system short circuited and we could only test for it by sticking our hands in the water. We turned the system OFF and my coworker got the worst of it and got shocked directly rather than through the water when she unplugged the heater that short-circuited. Had one hell of a headache the rest of the night and random muscle twitches all over.
One time when I was younger I stuck a bobby pin in a light socket at the hairdressers. I have no memory of this day, but I was told the power went out and my fingers turned black lol
Question: what is happening in your head when you stand up really quick and travel through space and time, and feel completely different?
here because as a new electrician, i learned it's extremely common to shock yourself on the job. like almost every day. but a 120v shock from any residential receptacle or light fixture feels at worst like those shock pens your uncle tricks you with. but a toaster in a bathtub from the same 120v circuit is certain death.
Dude if you're getting belted almost every day you're doing something wrong lol
great video and presentation
When Hank says things with the inflection as he does with "phone charger" at 1:35..........XD he does that a lot! Silly hanky
Thanks for helping me with my assignment im doing at midnight I love you
I scored a really long lead with a light socket on the end once. Utilised the hell out of it. Light wherever I wanted. Bear in mind this was back in the early 90s...but anyway. I had it plugged in with no bulb and my curious mind wondered what it would be like to get shocked. Perfect opportunity to find out. I had a plan, quickly tap the prongs with my finger tip and out again. Successful experiment. I felt a bit of a jolt, and a high frequency vibration, much like when you touch something vibrating at high frequency it hurts. That's what felt like, I don't know for sure if any vibration took place. A burn mark from one of the prongs topped it off.
I liked how in L4D2 you could revive someone who has "passed away" due to bullet wounds with electricity.
Awesome explanations *-*
I was shocked working on an old fridge and I started speaking a different language.
wth it took a whole month before youtube suggested this video to me... I been binge watching this channel. Just seems like this is the type of info that could be considered to be very pertinent in every day life. *slow clap for youtube algo*
On the bright side, you can only ever experience electrocution once.
I’m taking intro ee courses in college, you explain it better than my professor
I used to learn about electronics by messing with them and sometimes I got a little buzz and tingles on my hands.
Now that I learned an electrocution isn't as flashy and it doesn't take much to stop a heart, I know it wasn't just a weird feeling but the things were actually zapping me. I am kinda scared to keep on with my "practical research" now
The accepted boundary between safe voltages and higher voltages in electrical equipment is 42 V not 120 V as stated. Safety standards dictate increased insulation and physical protection from contact above 42V.
