The volt is the SI derived unit for electric potential and voltage (derived from the ampere and watt). It is named in honor of Alessandro Volta, who, in 1800, 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.
