Initially, when the switch in a series RL circuit is closed, the inductor acts as?(a) Open circuit(b) Short circuit(c) Resistor(d) Capacitor

Answer» Right answer is (a) Open circuit

Explanation: Before switch is closed, current in inductor is zero. When the switch in a series RL circuit is closed, current in the inductor remains zero since current in inductor doesn’t change suddenly. So, the inductor acts as an open circuit.
