WebElectric Potential Difference. The electric potential difference between points A and B, V B − V A, is defined to be the change in potential energy of a charge q moved from A to B, divided by the charge. Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta. 1 V = 1 J/C.
