As current is defined in terms of quantity of charge delivered per unit of time, there is a relationship between charge, current and time, given by: q = I t (or I = q/t), where: • q is the charge measured in coulombs (C), • I is the current measured in amps (A), and • t is the time measured in seconds (s).
Electric current is a flow of electrical charge. Electrical charge is measured in Coulombs \text{(C)} and current is measured in amperes \text{(A)}.The current can be thought of as the rate of flow of charge around the circuit. You can measure current using an ammeter. You can calculate the charge that has flown around a circuit in a certain time \text{(s)} using the following equation:
