The volt (symbol: V) is the SI unit of electric potential difference and electromotive force. It is named after the Italian physicist Alessandro Volta (1745–1827).
A similar unit, used for practical measurements of potential difference, is the conventional volt (symbol: V90).[note 1]
Definition
The volt is defined as the potential difference between two points on a conductor when the current flowing is one ampere and the power dissipated is one watt.[1]

Notes
- ↑ V90 is considered to be a physical constant, hence the use of italics for the symbol.
