Point Charges (1 of 10) Electric Potential An Explanation

Gives a conceptual and quantitative explanation of electric potential for point charges.

An electric potential is the amount of work needed to move a unit of positive charge from a reference point to a specific point inside the field without producing an acceleration. It can also be stated as the amount of electric potential energy per unit of charge. The reference point is typically at infinity where the electric potential is assumed to be zero. The SI unit is joules per coulomb (J/C) or the volt (V).

The electric potential energy of a system of point charges is defined as the work required to bring the system of charges close together from an infinite distance. An object has electric potential energy by virtue of two key elements: its own electric charge and its relative position to another electrically charged objects. The SI unit for electric potential energy is the joules (J).

We all have to work to achieve our highest potential, never stop learning.

I spent 2 hours trying to understand the difference between electric potential energy and electric potential by searching through Youtube and other websites. I've noticed that a lot of other science teachers try to draw a comparison between gravitational potential and electric potential for some reason. Maybe it's just me but I think that your way of tackling this concept is much more straightforward and effective than anyone else I've came across. Thank you so much!

I'm currently studying for the MCAT and have spent days trying to understand this concept. Thank you so much!

Please dont stop making education video like this, you help me alot understanding the concept

[mihirbose]

These kind of explanations are the one's That I think people crave ( I DO)
THANK YOU SO MUCH

After taking my final exam, your channel really helped me, so thank you

[bennabon]

omg, it's me who have to thank you, you just saved my physics life !

[enzomwinkeu]

Science never get old, the video is made 8 years ago but i still learning

[renadalharbi]

Usually, physics is my enemy, I really hate it.
You made it much easier for me :)
Thank you so much!

[hypnotize]

agreed, , but the world needs more teachers/ professors like yourself... we have ones that make things so hard its unattainable.
