Answer
The SI unit of electric current is the ampere (A), often shortened to "amp." One ampere is defined as the flow of one coulomb of charge per second. The formula is 1 A = 1 C/s (1 ampere = 1 coulomb per second). The ampere is one of the seven base units in the International System of Units and is named after French physicist André-Marie Ampère, who made significant contributions to electromagnetism.
