Figure shows a circuit that contains three identical resistors with resistance each, two identical inductors with inductance mH each, and an ideal battery with emf The current through the battery just after the switch is closed is

A
A
A
mA
To solve this problem, we need to analyze the circuit just after the switch is closed.Given:• Resistance of each resistor • Inductance of each inductor mHH• EMF of the battery VJust after the switch is closed, the inductors behave as open circuits because the current through an inductor cannot change instantaneously.Therefore, the inductors will block any current flow through their branches.This simplifies the circuit to only the resistors in series with the battery.The circuit now consists of:• One resistor in series with the battery.The total resistance is simply Using Ohm's Law, the current through the battery is given by:Substitute the known values:AHowever, since the inductors initially block the current, the actual current through the battery just after the switch is closed is ATherefore, the correct answer is A corresponding to Option 3.
