The difference of electric potential (V) between the two points (final and the initial location) when work is done upon a charge is the electric potential difference. The standard metric unit of potential difference is volt. If the electric potential difference between two points is 1 volt, then 1 Coulomb of charge will gain 1 joule of potential energy when moved between those two points. Use this potential difference calculator to find the potential difference in electrical circuits.
What is the electric potential difference (PD) of two points with electric charge of 15 C and energy storage of 20 Joules.
PD= 1.333 V.
