Can potential energy be in the unit of Volts?

Electric Potential (volts) is the potential energy per unit charge. So the potential energy of a charge q in a region of space with electric potential V is U = qV.

 

LOOK at the equation!!!!!!!!!!!!!!!!!!

 

you don't yet understand what you are looking at...getting angry with those attempting to get you to solve your problem, like me, will avail you nothing...I am trying to get you to THINK....not get angry....

Let's try it this way...suppose I said to you distance equals verlocity times time...d = vt, and asked you how long it will take to move a given distance at a given velocity.....
how would you approach that??

Use the same approach to your problem...

Also, this is NOT the forum for homework questions....

 

good...now you have the idea.....try here:

good luck...

 

Strictly speaking you can't. There is no "correct" way to express energy in units of volts in the SI system (Volt is a 'inoffically' a base unit, Joule is a derived unit).
However, since they in this case only differ by e it is not at all unusual for people to talk about potential energy in volts.

Also, there IS a way to write this while still using the right units (which is what some people do in research papers and other "offical" documents).
You should be able to figure it out by looking at the equation (which I suspect is what Naty1 is refering to)

 

How much electrical energy is stored in a 2200-milliamp-hour rechargeable NiMH battery?

Hi miamirulz29!

(btw, "joules" and "volts" have small intital letters )

I agree with you …

potential energy is in joules …

electric potential is potential energy per charge, so is in joules per coulomb, or volts.

(I've no idea what everyone else is hinting at )
