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.
Best Answer: Another term for voltage is potential difference; The SI unit of potential or potential difference is volt. Therefore, potential difference is sometimes called as voltage in practice. Potential at a point is the amount of work to be done on a unit positive charge from infinity to that point.eport Abuse. Voltage is measured in volts, which is a quantitative measure of the difference in potential energy between two charges (the energy of the system). Watts is a unit of power, which measures change in voltage over time.
