Ampere definition. Ampere or amp (symbol: A) is the unit of electrical current. The Ampere unit is named after Andre-Marie Ampere, from France. One Ampere is defined as the current that flows with electric charge of one Coulomb per second. 1 A = 1 C/s.
Amperage is a measure of the electrical current flowing through a circuit. Current is measured in amperes or amps. You must use the correct size wire for the amperage requirement of the circuit to prevent the wire from over heating. The number and type of electrical devices connected to a circuit determine the amperage requirement of the circuit.
