Yet people insist that Voltage kills. Albeit I say it is the Ampere that kills. Sure, hig hvoltage can kill if it generates enough Ampere on impact, which it can do in a Frequency network. But DC? Nah. Without ampere, you can't hurt a fly. Therefore, high voltage isn't necessarily Dangerous in the end of the day. The Ampere is.
@@Helveteshit You are forgetting another very important part: Delta t. Energy is proportional to delta t. Integral of power dt = energy. Energy is what kills. Current through the body is proportional to the power via I^2R=P. If it's only a nanosecond pulse width, probably won't hurt. Now make it one second, and you multiply total energy by one billion (assuming I=constant*[u(t)-u(t-T)] where T = pulse width). One billion (1,000,000,000x as much energy) and suddenly it's dangerous.
@@Helveteshit Also, Amperes are directly related to voltages by a very simple relationship. So the killer # of DC amperes (for example) requires some killer definitive DC voltage that is directly proportional to that # of DC amperes. If amperes kill, then the voltage required to produce that many amperes also kills to exactly the same degree. I think you may be thinking of capacity of a power source to produce a sustained current at a certain level (measured in Amperes)? Rather than just comparing voltage vs. amperes as far as which is more dangerous? V and A are mathematically related by a very simple proportional relationship in DC. Even in AC, Amps * Impedance = Volts. Impedance may vary with frequency, while resistance === impedance at DC.
Proof that for a lot of people, the ability to learn something more complicated, becomes infinitely easier with a good teacher/instructor/professor. This guy rocks.
Ok he's a great teacher yes but one thing you have to note is that he is teaching the basic fun stuff. Eventually when you get into the actual details of this and you see the math behind it, it becomes boring. He is not teaching the boring part of physics, which is the math behind the scenes
These are the kind of teachers that will preserve humanity for the future...I'm so glad they still exist. My sincere thanks to teachers like you sir. You make your students better people and this world a better place.
TheGreatSheikh I clicked on the video and was hoping to see someone comically fly across a room. I know, I'm horrible. (But IO wouldn't want to see someone die so I actually wouldn't want that to happen) But the video was very educational. I didn't know that's how currents and voltage went together. One time I put a plug in a socket, I felt and heard a buzz, then suddenly there was a flash, small fire, and a bright blinding light out of nowhere and it all happened in about 1.5 seconds. I got up went to the bathroom, looked in the mirror, and I was covered in black stuff. I can't remember what is was called (soot maybe?). That scared the hell out of me and I am not sure if that was a close death experience or not, or if it was common, but I know that no horror movie jump scare matched that moment. lol. Has that happened to other people a lot? Once I realized I was okay I just laughed for like 5 minutes. The whole wall within a 2-3 foot radius of that socket was also black and burnt, and that socket was no longer functional. Any idea what might have caused such an explosion? Poor wiring? Over use? Wear out overtime? That socket had been there for many 10s of years because I had that house for a while and never had that problem.
This is the best explanation I have ever seen in my life. I loved physics but never had a teacher that 'showed' me the physical phenomenon. As a person with ADHD, I really really appreciate and love this explanation. Thank you and best of luck!
Perfect example on how to teach kids something in a very good way and something they will remember for the rest of their lifes. Well done mr. Teacher - From a colleague teacher
Svmbah My teachers for science(s) from grades 7-12 have all been great. It's the english teachers that I've mostly hated. There was 1 really good english teacher though. I've had a mixed bag of teachers in everything except science/chem/physics.

This guy was very entertaining and informative. It made me appreciate my O'level physics teachers because I got almost the same demonstration (without the comment about lightening conductors - which was a revalation) when I was 13, and remembered it all. Well done Mr Benson in 1975

I'm liking this video, not because of the subject, but because we need more good teachers in the world teaching kids with passion like this. This is artwork.
"I'm not disappointed, I'm just confused, Why am I not dead?" *I hate to break it to you sir but the school staff is disappointed for you increasing their electricity bill.*
Electricity bill goes up when you draw current and in this experiment the current very low. Perhaps the light bulb raises the bill much more than these domes :-)
@@KamraanMir No, current is flowing through him. He's quite explicit about this. If you think that electricity *isn't* flowing, then you've missed the point of the whole lecture.
I’m a few years late but I just wanna say I’m impressed. I have ADHD so focusing is very difficult and I loose interest in this stuff quickly, I was just looking for a video to learn from for my exam tomorrow and found this video, it’s so fun to watch and I learnt! So thank you for making this interesting and fun enough for me to study with, I hope I do well!😄
This demonstration was a lot of fun for those kids, and I think it really brought the concepts home for them, but it was slightly misleading. It should be mentioned that when you put your hands on the source and the ground, the voltage across your body is *not* 200,000 V, it's far less than that, since the current is clamped from the source, the potential energy from source to ground is also clamped due to ohm's law. While the Van de Graaff generator can produce up to 200,000 volts open-circuit to provide a low current across a highly restive medium (like the air between the two terminals), it does not put that much across your body. :P It's not that current gets you and voltage doesn't, as such, the two are inextricably linked. :) And while an argument can be made that it's the physical flow of electrons (i.e current) that does the killing in the end, the more important thing is to make sure people understand that when they see a high voltage warning, that is dangerous, since voltage sources may *not* be current clamped like the Van de Graaff generator, and therefore may actually be able to maintain that voltage across your body, which is the case for the wall outlet. Similarly, kids shouldn't be scared of disconnected car batteries or bench power supplies, because even though those can provide plenty of current (power supplies can provide 3A short-circuit, which is more than enough to kill you), the car battery is clamped to 12 volts so it can only output around 12 miliamps across your body in normal conditions (since the impedance of your body is around 1000 ohms even when your skin is damp), and if the bench supply is clamped at a similarly low voltage (commonly 3.3V or 5V), it's likewise not going to be able to deliver enough current to hurt you either. So yeah, beware of high voltage and high current, because unless one of them is clamped low, either can indicate a potential hazard. A great video in any case, and thank-you for getting these kids interested in science and electrical engineering, that's totally awesome. :D
Glad you posted this. I never really got a solid grasp of the full concept and methods behind electricity and its properties. This sort of thing is helpful to read.
Yeah, I called shenanigans the minute he touched the nail to the ground electrode (after clenching my butt through his demonstration holding it a centimetre away). I figured it was probably a current limiter but he made it sound like a principle of science.
I had a physics teacher just like this guy. Enthusiastic, practical and is very good at explaining things in an easy way. This was the reason physics was my favorite subject at school, even though I don't really care for math and physics that much in general. Teachers like this should earn way more than the useless boring teachers. Unfortunately, the system is not made this way...
I noticed you stepped off the insulated stool and still were touching the high voltage with one hand at one point... I thought the rubber stool was the whole point that was keeping him safe... Or at the end, did he make the point that it was the current was never enough to hurt him unlike the current in something like the 120-volt outlet?
"If you tell me I will forget, If you show me I might remember, But, if you involve me I will understand" -- .and physics requires involvement... This guy is awesome...
Physics and similar subjects are so interesting and can be really fun but a bad teacher makes a bad experience, its unfortunate how many people lose interest in interesting subjects purely because of a bad teacher.
so in case if someone doesn't know. Voltage is the potential or difference of strength of two sources. current is the amount of electricity. Imagine a river, voltage is the incline, current is the water, and resistance is the width. without voltage (incline), no current (water) will flow no matter the resistance. adding voltage increases the flow. now if you go under a water fall will a super high voltage ( elevation) but little water (current) you will survive. same if you have a lake (lots of current) but no incline (voltage you will live). with both you will die. voltage forces current through the resistance. I hope I made it clear for some people.
I learned more about electricity through this video and the responses in the comments than my whole schooling. This was also so well explained and entertaining to watch, incredible teacher right there, thank you for this.
Its funny because today i was in the front row and while he was doing this everyone said hey, its not on! and he said i know its not on 😂 crazy how he said the same thing 5 years later

"I'm not disappointed, I'm just confused, Why am I not dead?"
*I hate to break it to you sir but the school staff is disappointed for you increasing their electricity bill.*
Electricity bill goes up when you draw current and in this experiment the current very low. Perhaps the light bulb raises the bill much more than these domes :-)
@@maojpatra so its 200k volts and low current?
@@albert_the_cool8092 it's not flowing through anything... That is what the whole lecture was all about
@@KamraanMir No, current is flowing through him. He's quite explicit about this. If you think that electricity *isn't* flowing, then you've missed the point of the whole lecture.

I thought touching electricity hertz
joey serenko DC has no Hertz.
I thought electricity running through walls are AC
Ha so funny
Sarcasm, obviously
Good try though
I just realised, how many years have passed. He is still a brilliant teacher.
Man this guy can make even the most monotonous topics come alive we need such teachers
I wish
This is such an amazing explanation by the coolest teacher with a huge sense of humor
I have never met a physics teacher, who didn't had humor. They go hand in hand. :)
him pointing electrons is one of the coolest thing I've ever seen in my life
Someone give this man a medal for his great lecture!
A rare species of teachers which are never found on this planet hats off
I swear someone said "A Pokemon move." When he asked what a Lightning Rod was.
EruditeWho the even sadder part is, they're not even right... Its an ability, not a move. Completely different
Magmafrost13 the even sadder part is that you know the difference.
HA!.... Got em!

no worries, lord helix will save us!
+Magmafrost13 Doesn't it negate all electric type attacks done to the pokemon? Also, a coincidence seeing you here.
You are a phenomenal teacher, truly the gold standard of what teachers should strive to achieve 😊🙌🤩
this guy is an awesome teacher! i already knew all this but the way he was teaching was very entertaining so I watched it anyway.

I know everything that is going on there... and I'm 15 years old.
amadeusz antyga give this guy a medal
amadeusz antyga As you should, this is common knowledge for even 13 yr olds.
I’m a few years late but I just wanna say I’m impressed. I have ADHD so focusing is very difficult and I loose interest in this stuff quickly, I was just looking for a video to learn from for my exam tomorrow and found this video, it’s so fun to watch and I learnt! So thank you for making this interesting and fun enough for me to study with, I hope I do well!😄
Good luck with your exam!
How did it go?
I'll see you guys at the next TH-cam Algorithm Meetup

This demonstration was a lot of fun for those kids, and I think it really brought the concepts home for them, but it was slightly misleading. It should be mentioned that when you put your hands on the source and the ground, the voltage across your body is *not* 200,000 V, it's far less than that, since the current is clamped from the source, the potential energy from source to ground is also clamped due to ohm's law. While the Van de Graaff generator can produce up to 200,000 volts open-circuit to provide a low current across a highly restive medium (like the air between the two terminals), it does not put that much across your body. :P It's not that current gets you and voltage doesn't, as such, the two are inextricably linked. :) And while an argument can be made that it's the physical flow of electrons (i.e current) that does the killing in the end, the more important thing is to make sure people understand that when they see a high voltage warning, that is dangerous, since voltage sources may *not* be current clamped like the Van de Graaff generator, and therefore may actually be able to maintain that voltage across your body, which is the case for the wall outlet. Similarly, kids shouldn't be scared of disconnected car batteries or bench power supplies, because even though those can provide plenty of current (power supplies can provide 3A short-circuit, which is more than enough to kill you), the car battery is clamped to 12 volts so it can only output around 12 miliamps across your body in normal conditions (since the impedance of your body is around 1000 ohms even when your skin is damp), and if the bench supply is clamped at a similarly low voltage (commonly 3.3V or 5V), it's likewise not going to be able to deliver enough current to hurt you either.
So yeah, beware of high voltage and high current, because unless one of them is clamped low, either can indicate a potential hazard.
A great video in any case, and thank-you for getting these kids interested in science and electrical engineering, that's totally awesome. :D

Your explanation would have put that entire auditorium to sleep.
U r right✋👌
Glad you posted this. I never really got a solid grasp of the full concept and methods behind electricity and its properties. This sort of thing is helpful to read.
Yeah, I called shenanigans the minute he touched the nail to the ground electrode (after clenching my butt through his demonstration holding it a centimetre away). I figured it was probably a current limiter but he made it sound like a principle of science.
I had a physics teacher just like this guy. Enthusiastic, practical and is very good at explaining things in an easy way. This was the reason physics was my favorite subject at school, even though I don't really care for math and physics that much in general.
Teachers like this should earn way more than the useless boring teachers. Unfortunately, the system is not made this way...
"Touching 200,000 volts can kill you"
Him: Here let me demonstrate.
I must say That is a very smart idea
It's all fun and games till the stool fails to lift him.
That would be a lot of doughnuts.
I noticed you stepped off the insulated stool and still were touching the high voltage with one hand at one point... I thought the rubber stool was the whole point that was keeping him safe...
Or at the end, did he make the point that it was the current was never enough to hurt him unlike the current in something like the 120-volt outlet?
@@BuffaloNickel9 yes as u said even the current was flowing through his body, it was not enough to hurt him
@@knseeker1524 so that that means the the resistance in the ball was too much that there wasn't enough current flowing through it?
@@ihaveagoal4665 its because of the resistance underneath him
"If you tell me I will forget, If you show me I might remember, But, if you involve me I will understand" -- .and physics requires involvement... This guy is awesome...
Anyone would be lucky to have a teacher like him.
200,000 volts? 200,000 subs? Awesome coincidence.
Trivago.
you are a tiny volt in a river of currents.

I think I learned more in this 8-minute video than I did in the entirety of my school year. You're a great teacher and I thank you for your services.
"Teachers who make physics boring are evil" you aren't one of them 😎
Physics and similar subjects are so interesting and can be really fun but a bad teacher makes a bad experience, its unfortunate how many people lose interest in interesting subjects purely because of a bad teacher.
Now this is called a good and entertaining teacher. I would love to have teachers like this
"Did you died?"
This man: "Yes but actually no."
Did you died?
schrodinger: that's my point
He was in a quantum super position and in our universe he survived, we saw the version of him that lived! Lol

so in case if someone doesn't know. Voltage is the potential or difference of strength of two sources. current is the amount of electricity. Imagine a river, voltage is the incline, current is the water, and resistance is the width. without voltage (incline), no current (water) will flow no matter the resistance. adding voltage increases the flow. now if you go under a water fall will a super high voltage ( elevation) but little water (current) you will survive. same if you have a lake (lots of current) but no incline (voltage you will live). with both you will die. voltage forces current through the resistance. I hope I made it clear for some people.
+Bayan Zabihiyan This was very helpful - thank you.
1:30 That is the kind of crowd I'd like to see when I am on the electric chair.
Oof
I learned more about electricity through this video and the responses in the comments than my whole schooling.
This was also so well explained and entertaining to watch, incredible teacher right there, thank you for this.
This is a shocking video, I'm just totally stunned at the quality and content
haha
"Shocking"

I already knew all of this stuff, but watched anyway. That is what I call a talented presenter.
I have tons of respect for ppl who enjoy what they do for living, this teacher is one of those
Its funny because today i was in the front row and while he was doing this everyone said hey, its not on! and he said i know its not on 😂 crazy how he said the same thing 5 years later
That's so cool tho
watt is love baby dont hertz me
oh no
DONT HERTZ ME!
Ohm no!
Don't hertz me, no more
oh no
I am crying at how good you are sir . That was the best explanation i have ever received from a teacher regarding current and electricity
