## Is this a correct definition of one volt?

One volt is when:
The difference in (electrical potential energy per unit charge (q)) between two places equals one.

Where electrical potential energy equals

EPE at distance R from charge Q = (1/4piEpsilonNought) * Q/R

Is this Correct?

Thanks!

 *When the source charge Q is spherical in a vacuum
 1 Volt equals 1 Joule per Coulomb.

## Is this a correct definition of one volt?

The equation I gave would have units 1 Joule per Coulomb, I'm just wondering if everything I said was correct
 Recognitions: Gold Member Science Advisor Staff Emeritus You may have known that "electrical potential energy per unit charge (q)" is in "Joules per Coulomb but no one else can until you say so! Electric potential energy, like any energy, can be measured in ergs as well as Joules, and charge can be measured in "electrons" as well.
