Noun. 1. potential difference-the difference in electrical charge between two points in a circuit expressed in volts. electric potential, potential drop, voltage, potential. electrical phenomenon-a physical phenomenon involving electricity.
Units for electric potential and fields Previously, we noted that electric forces are in Newtons (N), electric potential energies are in Joules (J), and charge is measured in Coulombs (C). Since electric fields and potentials are obtained by dividing the force and potential energy, respectively, by the charge they are measured in units of (N/C) and (J/C) respectively. But a Joule per Coulomb is also known as a volt (V), and the electric potential can also be referred to as the voltage.
