Electric potential difference

Vedclass · Answer

(B) The electric potential difference $(V)$ between two points is defined as the amount of work done $(W)$ in moving a unit positive charge $(Q)$ from one point to another.Mathematically,$V = W / Q$.The unit of work $(W)$ is Joule $(J)$ and the unit of charge $(Q)$ is Coulomb $(C)$.Therefore,the unit of electric potential difference is $Joule/Coulomb$ $(J/C)$,which is also known as Volt $(V)$.

Of which physical quantity is the $joule/coulomb$ a unit?
