Definition of Electric Current:
Electric current is the rate at which charge flows past a point on a circuit. Mathematically, current is the quantity of charge that passes through a cross-sectional area on a circuit per unit of time.

Definition of the Ampere:
The standard metric unit of current is the ampere (abbreviated Amp or A). A current of 1.0 ampere is defined as the current that exists when 1.0 Coulomb of charge passes by a point on the circuit in 1.0 second.
