- noun an SI unit of electrical potential, defined as voltage across a one ohm resistance when one amp is flowing
- The unit of voltage or potential difference equal to the voltage between two points of a conducting wire carrying a constant current of one ampere, when the power dissipated between the points is one watt.
- The SI unit for potential difference, electric potential, and electromotive force. A volt may be defined as the potential difference between two points along a conductor when the current flowing between them is held at one ampere, and the power dissipated is one watt.
- noun a measure of potential electrical force.
