**Volt Definition:** The amount of work done expressed in joule in bringing 1 coulomb of charge, starting from any point of an electric circuit and transversing the entire circuit including the cell and back to the same point is equal to the electromotive force expressed in volt.

A “volt” is a unit of electric potential, also known as electromotive force, and represents “the potential difference between two points of a conducting wire carrying a constant current of 1 ampere when the power dissipated between these points is equal to 1 watt.”

One Volt is defined as energy consumption of one joule per electric charge of one coulomb.

1V = 1J/C

One volt is equal to the current of 1 amp times the resistance of 1 ohm:

1V = 1A ⋅ 1Ω

The Volt unit is named after Alessandro Volta, an Italian physicist who invented an electric battery.

**Volts to watts conversion:** The power in watts (W) is equal to the voltage in volts (V) times the current in amps (A): watts (W) = volts (V) × amps (A)

**Volts to joules conversion:** The energy in joules (J) is equal to the voltage in volts (V) times the electric charge in coulombs (C): joules (J) = volts (V) × coulombs (C)
