A) the circuit must be interrupted.
B) five time constants must have elapsed.
C) the voltage drop across it must remain constant.
D) none of the above.

Quizplus · Accepted Answer

In an inductor, the time to reach steady state after a transient event is typically considered to be five time constants (5τ), where τ (tau) is the time constant of the inductor circuit. This period allows the current and magnetic field within the inductor to stabilize.
