What is Voltage?

Voltage is the electric potential difference between two points and is defined as the work done per unit charge to move a test charge between those two points. But how does all that relate to electricity? In this video, we'll show how electric charges can build up on surfaces, known as "static electricity," and how those charges can be used to define voltage. Obviously, a static electricity demonstration requires the creative use of balloons.

It's been 2 years that I haven't understood what voltage actually means. All I've heard from my teachers is that it's the difference in electric potential, but no further demonstration. Thank you.

for some reason, voltage is never clearly explained, it's all about amps, charge etc, so that was a big help!

Respected *Shawn Hymel* sir,
I am a student, and literally the way you have teached electricity and electromagnetism is infinite wonderful!❤️ You have given us knowledge in the best way which nobody has ever given to us!
In india, teachers don't teach us correctly, they just make. Us gulp the text written in the book.
I request you teacher Shawn hymel that please try to teach us more physics like that you did in past(electricity, electromagnetism)
I know making more such videos will take a lot of effort! But please try to help,
Please reply teacher🙏🙏🙏👍❤️😁

I’ve been doing physics for 2 years but this is the only thing that’s actually taught me what voltage literally is

[tedlahm]

Fantastic video. Powder coating info. is totally new to me.

[nayeemmotu]

I don't know why these type of videos are so underrated

[rm]

I’m not sure why these videos don’t have more views. They are simple, informative and fun. Just pure gold!

At 4:20, "Even if I had no positive particles, the potential between the two points is still 10 volts." Which two points?

This video is marketed as a kind of beginners guide to voltage, but it took me a lot of googling of certain concepts until I could eventually come back and fully understand the video. I think certain things in the video could be explained in more detail to give a holistic understanding of voltage.

Finally understood the SI unit of Volts! Thx

[bobojoe]

Only man on YouTube who can intuitively explain what voltage is. Thank you

[alexobzor]

Hello, it's really nice, that you combined a couple of formules like charge, energy, work, and then you created a definition of voltage. I really wanted exactly this casual relationship to understand, what voltage is. Because, here we have kinda wishy-washy thing that voltage is 1J/1C, and also we have ohms law, where we can define voltage from V=IR. But yes, I understand that Ohms law is more suitable for curcuits, but i am a beginner in this all stuff, and can it confuses me.

[ayushkatale]

You just cleared my doubt of 1 month, ☺☺☺☺

[dinayana.sproductions]

Thanks for this explanation. You solve my 1 and half years problems

[ochiorbus]

This one of the best explanations I saw on this subject

[wjldb]

Excelent explanation!! Very good for visualizing what is Voltage. As you said, the further i push one charge away from the other, more energy i would have to use to move it and so more electric potential energy would accumulate, right? But the more i push a magnet away from a metal object, it seems to lose the binding energy between them until a point where it no longer moves the object. Why are the attraction forces reducing instead of building up?

[anteconfig]

I feel like theres something i missed.
I still don't understand what voltage is.

I know that Watts = Volts * Amps but people keep telling me that voltage is like pressure which is really confusing.

It's confusing because if it was like pressure that means that there are many electrons in one area all repelling each other. and I know that in order to put these electrons in that situation that they have to be moving, but the math tell me that I can have high pressure with little motion... (e.g 1watt = Volts * Amps).

I know that like charges repel and I know that moving charged particle create a magnetic feild, also I know that two like charged particles traveling in the same direction will create a magnetic feild that makes an attractive force.
(idk the math) but that force to me isn't strong enough to create a high voltage at a low current.

I'm just really confused...
You say that voltage is the electric potential difference between two point. I'm assuming that those two point are unlike charges (e.g. the negative terminal and positive terminal). I could think of that as the potential energy of a ball held up high above the ground.
But so far it hasn't clicked...
Am I stupid/dense? Can someone help me? Am I beyond help?
I'm starting to believe I don't understand anything at all.
Also what's the maximum amount of voltage you can have inside of 1 Watt? there has to be a limit right?

[harikamopada]

very pleasure to watch your video.I could understand more easier.thank u so much

[chadchad]

I don't really understand why people are trying to explain the idea of voltage as potential energy between two points. For those aren't highly skilled with the use of physics definitions, won't understand it. Here's what I didn't understand and I believe explaining it this way would be much more simplier: voltage tells us how many WORK 1 charge is going to produce when it goes from A to B.

Just a little clearer than
Thank You for oyur efforts
