Introduction Electric current is the rate of transport of electric charge past a specified point or across a specified surface. The symbol I is generally used for constant currents and i for time-variable currents. The unit of current is the ampere (1 A = 1 C/s; in the SI system, the ampere is the basic unit and the coulomb is the derived unit). Ohm's law relates current to voltage and resistance. For simple dc circuits, I
