After long time an inductor behaves as a resistance-less path. So current through cell I =(12/ R / 3)=3 A ∵ R =12 Ω

Q. Three identical resistors with resistance $R = 12 Ω$ and two identical inductors with self inductance $L$ $= 5 m H$ are connected to an ideal battery with emf of $12 V$ as shown in figure. The current through the battery long after the switch has been closed will be ______A.

After long time an inductor behaves as a resistance-less path.
So current through cell
$I = \frac{12}{R /3} = 3 A {∵ R = 12 Ω}$
