Q. Figure shows a circuit that contains four identical resistors with resistance $R=2.0 \Omega,$ two identical inductors with inductance $L =2.0 mH$ and an ideal battery with $e m f E =9 V$. The current $' i^{\prime}$ just after the switch 'S' is closed will be :Physics Question Image

Solution:

Just after the switch is closed, inductor will behave like infinite resistance (open circuit) so the circuit will look like

$i=\frac{9}{R+R}=\frac{9}{4}=2.25$
