Electric Potential Units Explained

Volt (V)

The SI unit of electric potential, defined as the work done per unit charge. Also expressed as joules per coulomb. 1 V = 1 J/C.

Common uses: Household electricity, battery ratings, power supply specifications, electronic circuits.

Watt/ampere (W/A)

Alternative SI expression of electric potential, derived from Ohm's law. 1 W/A = 1 V (equivalent to volt).

Common uses: Power calculations, resistance-voltage relationships, circuit analysis.

Abvolt (abV)

CGS electromagnetic unit of electric potential. 1 abV = 10⁻⁸ V. Very small unit rarely used in practice.

Application: Legacy scientific calculations in CGS-emu systems, historical physics literature.

EMU of Electric Potential

Electromagnetic unit in the CGS system, equivalent to abvolt. 1 EMU = 10⁻⁸ V.

Note: Part of the CGS-emu system, largely replaced by SI units. Used primarily in historical context.

Statvolt (stV)

Electrostatic unit (ESU) of electric potential in the CGS system. 1 stV ≈ 299.79 V.

Application: Historical physics, theoretical electrostatics, CGS-esu calculations.

ESU of Electric Potential

Electrostatic unit, equivalent to statvolt. 1 ESU ≈ 299.79 V. Part of the CGS-esu system.

Note: Primarily used in theoretical physics and older scientific literature. Rarely encountered in modern applications.
