Volt is the electrical unit of voltage. One Volt is defined as energy consumption of one Joule per electric charge of one Coulomb.

: a unit of electrical potential difference and electromotive force equal to 1.00034 volts and formerly taken as the standard in the United States

In the International System of Units (SI), an electric potential is expressed in units of joules per coulomb (J⋅C −1), or volts (V). The volt is named after the Italian physicist Alessandro Volta (1745–1827).

The volt is the SI unit of voltage, electric potential difference, and electromotive force (EMF). It quantifies the potential energy per unit charge between two points in an electric field.

Voltage, also known as (electrical) potential difference, electric pressure, or electric tension, is the difference in electric potential between two points. [1][2] In a static electric field, it corresponds to the …
