Definition and History

The volt is the base unit of electric potential, voltage, and electromotive force in the International System of Units (SI). It is defined as the electric potential difference between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points.

The volt was named after Alessandro Volta, an Italian physicist and chemist who is credited with inventing the electric battery. The unit was originally defined in 1881 and has been refined over time to provide the most precise definition possible, making it fundamental to all electrical measurements and calculations involving voltage and electric potential.

The volt is equivalent to one joule per coulomb, making it the fundamental unit for measuring electric potential difference, voltage, and electromotive force in all electrical and electronic applications worldwide, serving as the basis for all other electrical potential units and measurements.
