SI unit of voltage is the Volt (V).

The SI unit of voltage is the volt (V), named after the Italian physicist Alessandro Volta. Volt or voltage is represented by the letter V.

Voltage, also known as electric potential difference, measures the electric potential energy per unit charge between two points in an electrical circuit. One volt represents one joule of energy per coulomb of charge. The symbol of volt or voltage is V.

Voltage is a fundamental concept in electricity, driving the flow of electric current through conductors and determining the behaviour of electrical components such as resistors, capacitors, and inductors. It’s a critical parameter in electrical engineering and is used extensively in designing and analyzing electrical systems and devices.
