David explains electric potential (voltage). Created by David SantoPietro.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

I'm upset that my education sometimes relies on professors who have phDs, but they don't know how to convey a message across to their students. They are smart, but cannot teach. I need to pass Physics to graduate and I am glad these videos are here to help me to do what my professor can't.

[KieranCondon]

It should be a fundamental human right to have access to this video (and more particularly this teacher)

[fgronzanicancun]

really, really thanks, this is the best explanation of eletric potential in the entire youtube.

[wendyma]

this explains
the. MOST. confusing thing I've ever learned in physics. thank you so much I had a brain explosion.

[johngalvin]

This single video is without a doubt the standard to which all education should be set- the clarity of something that can be so confusing in text or lecture astounds me. Thank you Khan Academy for everything you give students

[JYDemir]

Physicists really need to come up with better terminology. Are they purposely trying to confuse us... ?

1:21 "Stick a big ol' charge in here."

Why did I start laughing all the sudden?

[abdoennajah]

That's the clearest explanation i've found on youtube! Thanks a lot

[Chulito_con_frito]

You have no idea, I've been struggling with this concept for so long and I finally get it I just needed it broken down like that! Amazing teacher thanks for the video.

[BoZhaoengineering]

This is a deadly most wanted technical clearance ever in physics. I was so confused with potential and potential energy and the work done related to them. Now it is clear. I appreciate it very much.

[bonitachica]

I have been waiting for the longest time for a video on this. THANK YOU!!!

[faiyazkabir]

Our physics book says a lot of things to make physics look fun, but at the end of the day they took all the important stuff out. Thank you very much for the video

[manjularamesh]

Best explanation I ever had just amazing😘

[reetichauhan]

I need this guy to be my physics teacher😭

[tortugatech]

This is all when using a reference point at infinity, if he explained both with a random reference point, this would be the best video ever created...

[krishnakoppoju]

I have only one word for this video - AMAZING

[aktailakamangeldinov]

Does it matter who does work on it :external force or electric field?I mean, what if there is a negative charge instead positive?

[madeleinehermans]

This is the best explanation for e potential/potential energy that I have ever seen. I finally understand now

[mahmoudashraf]

so whats the difference in concept between E=V/R and E=F/q

[wangecindirangu]

David is the best! Very effective at explaining these complicated concepts
