An inductance L and a resistance R are connected in series to an ideal battery. A switch in the circuit is closed at time 0, at which time the current is zero. The energy stored in the inductor is a maximum: A) just after the switch is closed B) at the time t = L/R after the switch is closed C) at the time t = L/R² after the switch is closed D) at the time t = 2L/R after the switch is closed E) a long time after the switch is closed

Question

Quizplus · Accepted Answer

The energy stored in the inductor is maximum when the current reaches its steady-state value, which occurs a long time after the switch is closed.
