amount of current passing a point in the circuit each sec
Current. The transfer of charge (i.e. moving charge) is called current. More specifically electric current is the rate of flow of charge i.e. the amount of charge passing a given point in a circuit each second.The unit of current is the Ampere (A) and 1 Amp is therefore 1 Coulomb of charge passing each second.1 A = 1 C / s.ore specifically electric current is the rate of flow of charge i.e. the amount of charge passing a given point in a circuit each second.
