Thanks for sharing the video
First time
Make sure that works
FINALLY I understand voltage :) Thank you Paul
Thanks for
The easiest way to explain it would be to think of a battery. Nature is about balance. You know that when you put the positive side of a magnet close to the negative side of another magnet, they're going to try to pull together. They're trying to "balance" themselves.
Now think about that with electrons. The electrons in the negative side of the battery really REALLY want to get to the positive side. We take advantage of this by creating circuits. We give them a path to get to that positive side that they desperately want to reach, and we have them do a little work for us along the way. The MORE free electrons in the negative side of the battery, the more POTENTIAL there is for us to use (Voltage).
This is why a fully charged battery will read its rated voltage, or close to it, and why a depleted battery will read a noticeably LOWER voltage -- reflecting the fact that many of those electrons are now at the positive side of the battery. There aren't AS MANY of them left that need to get over there anymore, so much of the FORCE they provide when traveling through the circuit has dissipated.
Think of a bunch of people waiting outside a store before Black Friday. All of those people are electrons. Outside the store is the negative side of the battery. The store itself is the circuit. The register is the positive side of the battery. As soon as those doors are open, those people are going to rush to get to the items they want, grab 'em, and run for the registers! The more people (electrons) there are waiting in line (negative side), the more FORCE they'll have when they make their rush to grab what they want and checkout (positive side).
I hope that helps.
Not so much help its actually magic, I FINALLY understand. THANKYOU
There is not another TH-cam comment that has been more useful to me than this one. outstanding explanation dude
@@hania_khan396 You're very welcome. Glad to help. It's a bit confusing to grasp when you're unfamiliar with it.
@@derpderpinson7449 Glad to help! It took me a while to grasp it completely myself. Once I did, I'd figured an explanation like this would be helpful to others.
Thank you for the explanation, but I don't understand the meaning of potential flowing from high to low. Doesn't this mean electrons should flow from plus to minus?
This channel got me feeling like I could become an electrician
You should, its an amazing trade! Changed my life.
Or an Engineer!
Shaine MacDonald idk man I’m not tht smart
@@mattm5941 I never thought I was smart until I forced myself to get an A in calc 1 with no prior math experience outside of algebra. Most people have the ability to learn things, but they believe that they can't. If you try hard enough and actually believe that something is possible, theres a very good chance that you can do it. Don't put yourself down.
Or an electric engineer!
Man, its a shame my school didnt teach electricity this way. Great educational material, thank you sir!
Sir? i didn't know he was knighted?!
You have some of the most well explained electronics videos I've ever seen on YT. Really great work with the visuals as well. I feel like my years of electronics knowledge really clicked into place and made it more real rather than abstract, as any field in STEM can get. Thank you so much for these videos.
ikr they help me so much
I studied automotive at Lincoln tech and the electrical course which were two classes was by far my favorite part of school. I really love the way it all works and this channel is great!💡
This is a very helpful visual representation. Thanks for making these videos!
I wish I had videos like this when I was in school and college 😭
It means that as i am student i gotta take it so seriously.
Same feeling 😪
Same bruh😭
Lol😂
Same feeling 😔
Ive been doing physics for 6 years but never really understood what voltage was until now , thanks a lot
you can only learn when actually want to learn..
I forgot again
Wonderful. Pressure can not be seen under a microscope. It can be measured by using the proper gauge. Flow (current etc) can be seen under the proper microscope ( electrons in a metal, atoms in water.)
@@tedlahm5740 can u explain it to me is it the diff between the positive and negative terminal ?
@@a1_himanshighangas_231 Yes, one end pulls the electrons (positive side) other end pushes the electrons (negative end). REASON BEING opposites attract + and -
WHILE likes repeal (- and -). Direct current circuit.
CURRENT is the number of electrons that are moving inside the conductor passing
one point in a second of time. ( current, measured in ampers)
I've honestly understoom more in this 10 minute video than these past few weeks of my college class AND lab (don't know if that's a good thing or a bad thing lol)
This is what I was looking for to learn the basics of Electrical Engineering. Thanks man.
Thank you for this. I struggle with these concepts but now I'm starting to get it, especially series vs parallel.
Fun fact....here in Brazil there are cities that are 110v while other cities are 220v. My city is 110v and my neighbor city is 220v. It's a mess haha.
Best thing here is when you move between cities with different voltages and have to either discard some of your appliances or adapt them
When my mom moved to my state's capital (which is 110v) she had her kitchen wired to be 220v in order to keep the fridge, then when she bought a new microwave oven she bought a 220v one... now she's moving to a new apartment where she can't change the kitchen voltage and I'm getting the microwave oven because I now live in a 220v city lmao
@@arsnakehert you should post this on reddit stories cause damn, that's one hell of a story.
Imagine to be an electrician living in a 110 v city and then he moves to a 220 v area, very dangerous
Wtf haha, buying appliances is harder then?
lol
I like these videos. I'm surprised by how many electrons are needed to flow per second. It's also interesting how you can change the voltage by the way you configure the power lines. Thanks for the content.
Thanks mate for the excellent video. After 53 years this lucid explanation has clarified the concept of what a volt is.! Phew!
As a licensed Electronics Engineer, I learned more by watching 30 minutes theses videos than 5 years of Engineering + 5 Months of Board Exam Review
you must be sitting in last row and not paying attention to lectures.
@@kamvc72 hakdogs
what? this is only a 1 lesson in highschool physics, there's no way this video has taught you more than 5 years of engineering..
@@Z7youtube School is highly archaic (Its exaclty the same model since at least 500 years), teach you to stay a slave worker to consumer for free illimited ressources (most of the time I mean)
TH-cam teach how to be free if you get the good channels.
Thats why Schools are called Schools, they skrew you even if we learn basic things that are really needed.
Thats why youtube is called youtube, Its about you.
Thats why Play Thoughts is called Play Thoughts, he need a good explainer or his thoughts playing.
Thats why Im called Darktrap, From the darkness comes Light, I trap the darkness.
And it goes again and again ... like COD
What this video has covered has been taught in Higher Secondary. How did you manage to get into engineering 😂 and that too Electronics engineering. Management Quota???
Dude I'm really loving your videos. Well done. Much appreciated:)
I didn’t understand a single sh!t about this on other channels. This one ☝🏼 is the best. Understood every word
Finally a water analogy that is actually compelte since all others just start comparing it to a water hose that actually doesnt have a return.
HA!!! I get it!! I now understand why the term potential difference is used. Whilst understanding how to apply and measure it, I never knew what it meant. Your videos are absolutely wonderful at explaining to someone who is just learning. Thank you so much, I appreciate all the hard work you have put into these.
Love the way you explain things. I'm in my 50s learning electronics for cars and get confused when told volts in a battery and volts in the circuit my brain keeps telling me it should be amps in the circuit and volts in the battery. But I like the way you teach. Haven't got it yet but you push me in the right direction thank you
Respect to awesome people like you out there in this world man ..!
Thankyou very much this is the best explanations.
Thank you in advance,
And also thanks for creating such a valuable resources to the community, great content easy to follow hence understand 🙏🏿🙏🏿
this is great. Have been leaarning about electricity for the last few months but haven't been clear with the concepts. This video has helped me clear the basics
I really liked this video thanks so much. Other sources don't use animations and so its harder to process. I'm an engineering student so I'll really recommend this video to other engineering students
Best channel ever
Learned more with your 10+ minute video than I ever had know-Thank You!
Best video ever to learn electricity basics. SUBSCRIBED!
The best explanation of voltage that I've come across. Thank you!!!
HUZZAH! Most quality and informative videos I’ve ever watched
True
huzzah indeed
I cannot express my thanks to your channel enough. I hate things that are over simplified and a feel restricted in my electrical classes at points.
I knew youtube videos could be educational... but now after watching this my brain is twice as big. And all for free. Thanks!
That was pretty awesome to learn. I had no idea placing batteries linearly versus side by side played any difference.
Electric basic was explained in simple and easy way.Appreciated
SO much needed this videos back in 2009. Thank you very much mate!
What a great explanation. I was I had that when I was in school.. Great work!
Thank you for the explanation about the battery you said if you split them the light would last longer and if you put them together the the light will be brighter I give this video a thumbs up👍😁
That's why the batteries in our TV remotes are in parallel.
Woooah.
Check this out, how a battery works: th-cam.com/video/PXNKkcB0pI4/w-d-xo.html
@@rravitejamavr6650 i think they're actually in series. as far as i know, most battery packs that use these batteries put them in series
Damn dude you are smart! Great channel!
The channel is super helpful! Thank you for sharing! I am starting to pursue HVAC carreer!
Thank you for the video . The information and explaination of parallel circuit and series circuit are simple to understand .
Thanks! I am a doctor and I really enjoyed this video.
Thank You, great video for this American who is trying to learn the basics of electrcity.
Please keep it up.
Do you have videos on the different levels of multimeter use, starting with the basics and what the symbols are/mean?
Would also like to learn how to check a capacitor on American HVAC with a multimeter.
Not yet but they are in the pipework
@@EngineeringMindset I think you need more voltage!
Check our new Multimeter tutorial out ➡️ th-cam.com/video/4lAyzRxsbDc/w-d-xo.html
this is a great video, thanks a lot for the great effort 👍
man we need more people like you, great channel keep it up
I swear this shit is magic i try so hard and still just cant grasp how
explaining voltage with an analogy is ok to start with, but what actually is it , i know it like a pressure , but what causes it ?
Take a battery, on one side it has too many electrons, on the other it needs electrons, so upon connecting the 2 sides with a wire the electrons will naturally go to the positive side, voltage is basically how much negative charge is separated from the positive (hence potential difference). So a voltage is potentially how much energy the electrons would give off while travelling from the negative to the positive part
@@warmusblanketus9729
Is every material that exist in this world has voltage ?
@@mohdrozakhiismail7273 not voltage but they have resistance
@@warmusblanketus9729 what and how many material in this world that already has a 'build in' voltage into them ?
If there is
If none, then how to create voltage ?
Thank so much for your help, im very greatfull to you for this.
@@mohdrozakhiismail7273 voltage is "created" when there are at least 2 substances, one of which is positive (has fewer electrons) and the other is negative (has too many electrons), between these two is a potential difference (voltage) which means that by connecting them with a conductor like copper, electricity will start to flow from the negative to the positive side. If a material had a voltage on its own then theoretically it would always have electricity running through it
Amazing channel. You do a great job, thank you!
You guys are going to make me start getting back into electronics again I miss all this
the best goddamn explanation i've ever seen, tnx
Super useful video! Thank you very much for making this and sharing it with us. A quick question if you will, please. I am curious to know if countries that are on the 240+V system are more inefficient? Thinking about this in terms of climate change and if it would be more beneficial if we all adopt one system over the other.
actually, 240V is more efficient than 120V since you need lower current for the same amount of power. lower current = lower voltage drop in the wire = less wasted energy
Thank you for your effort
I haven't subscribed to your channel for a long time, it's been almost two years, so that video is all about it.
"Huzzah"
You made an excellent video explaining voltage! One remark though, at 3:35 you say the light will be dimmer when two batteries are in parallel. This is not true -unless you ment it relative to two batteries in series. You probably ment the latter, but now it sounds as if you ment to say the light will be dimmer relative to just one battery.. Suggestion: add text saying "dimmer relative to two batteries in series".
Yes I meant relative. Unfortunately YT no longer allows text on screen if a clickable link in used.
I would like to see a short bit on Continuity!
I own Rental Houses and can’t tell you how often I use Continuity for diagnosing a SPRINKLER WIRING issue!
Good job with the site though!
I like it a lot!
Brilliant set of videos… thank you so much
How I wish this video was around when I first learned about voltage in the ninth grade... I was a year too early ;(
This is what I call a quality content video that gives you really useful information, compared to the meaningless Kardashians-style videos.
Keep on your good work!
Huzzah! I’ve always struggled with keeping the concept of voltage (and current etc) in my brain regardless of analogies, but I’m no dummy. Highly educated and a successful engineer, but always keep coming back to this stuff. It’s slowly starting to stick!
brilliant video mate, really clarified a lot for me.
huzzah!
Thanks finally I found something very educational rather than those shitty tv series. Thank you sir.
Amazing!! Would have been an eletrician had I discovered this channel 10 years back!
Perfect explanation ❤️ Thanks a lot
Huzzah!
How does a 9v battery differ from a 3v battery. Is it that the 9v battery has more electrons in its -ve terminal compared to the 3v battery or do they both have the same number of electrons in the -ve terminal but the 9v battery keeps its electrons at a higher pressure. Is it volume of electrons that is different or is it pressure? If it is pressure , does it mean that 1amp of current coming from a 9v battery source can do more work than 1amp coming from, a 3v source.
Good question and nobody answered. Go back to thinking of water,, a big pool has more water than a small one and so has more potential or volume and so will flow longer., verses a very tall very thin water tank that has as much volume of water as the big pool.. On the big pool you could have a big or small drain, and the same for the tall tank.
So you could adjust the valves of the big pool and the thin tall tank tank to flow out at exactly the same volume. The valves are the resistance. So if you crank your 12 volt battery car to start which is the valve fully open the battery will drain fast but it will crank. A one volt battery will drain so fast the starter will not even turn..
It is already explained in the video , the 9v battery produces 9 joules of energy per coulomb and the 3v battery produces 3joules of energy per coulomb.so at the end,the 9 v battery gives more energy and makes the electrons move faster
Check our our new car battery explained video: th-cam.com/video/VnPRX5zQWLw/w-d-xo.html
You made this so easy to understand. Great video.
Nice. Thanks for the info.
How is electron and voltage is produced? Thank you.
Watch this th-cam.com/video/mc979OhitAg/w-d-xo.html
Good question
My friend literally just told me “WhAT iS TiN fOiL MaDe OF?!”
I’ve been wondering my self
Generally not tin, but aluminium xD
John Jones oh yeah i forgot about that i guess me and him are equally dumb.
So much to learn in the most satisfying way...❤❤
Huzzah! XD (and thank you for these vids! I am having a hard time grasping the electrical system in vehicles so I'm trying to find videos like this to understand it better)
*summary:*
- voltage is the potential difference across a wire
- *voltage* can exist without current (like pressure on bottom of closed water container)
- *DC* is when electron flow is only in one direction
- *AC* is when electrons switch between flowing one way and another
But in ac we use high voltage transmission to reduce current!! Pls rply
Yes correct. If HIGH CURRENT (amps) were in transmission lines we would
need a cable the size of a Volkswagen. To get the same power. Not practical.
thanks for the analogy. very useful. i knew most of it but needed a refresher.
Nicely explained..sir
So more voltage=more power? So in sci-fi adding more “power” to the shields is just applying more voltage?
I know this a simple topic but all the videos I have seen don’t compare in terms of it’s explanations of voltage, volts, and current. Thanks for the video
Wow, best explanation I heard! Thank you!
Diz videos make Engineering very easy 2 comprehend...Great job..
Great Video, Super Helpful! Thanks 👍
Great video ...! On the topic
Excellent. You explained very well. Thank you. Keep up the great work.
Appreciate your videos greatly! Thank you
absolutely loving these explanations. Has helped me a ton with explaining how our electrical devices work to my elementary class. Just friendly note typo at 4:28
Thanks a lot for this video. This really helped me a lot, and now it is easier to understand what voltage means :)
Great channel, excellent vids!!!! Thanks a lot for sharing!!!!👍👍👍👍👍👍
Amazing explanation and greatly simplified.
Well explained. Shared with my little brother :)
Outstanding presentation and explanation!
wonderful explanation and graphics. Keep it up.
Excellent Explanation 👍👍
Thank you!! It helped me a lot.
I have learned my electricity chapters but once I think about potential difference or voltage. My all concept become confusing this video helped me alot
Awesome vid! Very informative!
Another awesome video. I always love understanding electricity. Now I am better than most around me🔌
Lovely Examples given for easy understanding
Thankyou, you have made the info much easier to understand.
I didn't got the concept understanding in schools but now i have understood it thanks to you
Beautiful explanation!!!
