Volt Definition and Usage

Voltage is a measurement of electromotive force and the electrical potential difference between two points of a conductor.[1] One volt is equal to the potential difference that would move one ampere of current against one ohm of resistance.

The volt is the SI derived unit for voltage in the metric system. Volts can be abbreviated as V; for example, 1 volt can be written as 1 V.

Ohm's Law states the current between two points on a conductor is proportional to the voltage and inversely proportional to the resistance. Using Ohm's Law, it's possible to express the potential difference in volts as an expression using current and resistance.

VV = IA × RΩ

The potential difference in volts is equal to the current in amperes times the resistance in ohms.

Background and Origin

The volt is named for Italian physicist Alessandro Volta to honor his pioneering in electricity. The volt was proposed and named for use as a unit of electromotive force in the late 19th century.
