Electrical Units

Named after André-Marie Ampère, measuring the volume of electrons flowing past a point per second.

1 Coulomb per second

The SI unit of electric charge, defined as the quantity carried by a current of one ampere flowing for one second.

1 ampere-second

The SI unit of capacitance, named for Michael Faraday, measuring a conductor's ability to store electric charge.

1 Coulomb per Volt

Named after Heinrich Hertz, tracking alternating current wave cycles.

Cycles per second

Named after James Prescott Joule, representing energy expended by an electric current.

1 Watt-second

The SI unit of electrical resistance, named for Georg Simon Ohm, whose 1827 work established the relationship between voltage, current and resistance.

1 Volt per Ampere

Tracks electric potential pressure pushing current through an electrical circuit.

1 Joule per Coulomb

Calculates structural power expenditure matching Volts multiplied by Amperes.

1 Joule per second
