amperes
Coulombs per second
Amperes are units of electric current, measuring the rate at which electric charge flows through a conductor.
Named after French physicist André-Marie Ampère, the ampere is one of the seven base units in the International System of Units.
Usually shortened to amps in everyday speech: The circuit breaker is rated for fifteen amps.
