Series RL Circuit

A resistor–inductor circuit (RL circuit) is an electric circuit composed of resistors and inductors driven by a voltage or current source. The time required for the voltage to fall by a factor of 1/e is called the RL time constant.

The RC time constant equals the magnetic inductance divided by the electric resistance.
