Volt

The volt (symbol: V) is the SI derived unit of electric potential difference. The number of volts is a measure of the strength of an electrical source in the sense of how much power is produced for a given current level. It is named in honor of Alessandro Volta (1745–1827), who invented the voltaic pile, the first chemical battery.

The volt is defined as the potential difference across a conductor when a current of one ampere dissipates one watt of power. Hence, it is the base SI representation m2 · kg · s-3 · A-1, which can be equally represented as one joule of energy per coulomb of charge, J/C.

Potential difference: Potential difference is a quantity in physics related to the amount of energy that would be required to move an object from one place to another against various types of force. The term is most frequently used as an abbreviation of 'electrical potential difference' (see below), which is almost synon...
