The name given to the rate of flow of electric charge is "electric current." Electric current is defined as the amount of electric charge flowing past a point in a circuit per unit time. It is measured in amperes (A), where one ampere equals one coulomb of charge passing through a point in one second. The formula for electric current is I=QtI=\frac{Q}{t}I=tQ​, where III is the current, QQQ is the charge, and ttt is the time interval.
