An inductance L and a resistance R are connected in series to an ideal battery.A switch in the circuit is closed at time t = 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 reaches its maximum a long time after the switch is closed, as the current in the circuit stabilizes to its maximum value, allowing the magnetic field around the inductor to reach its maximum strength.
