Three identical resistors with resistance $R = 12 Ω$ and two identical inductors with sell inductance $L = 5 mH$ 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________ $A$ .

Question

Aicharya · Accepted Answer

We know that after long time an inductor offers zero resistance i.e., in steady state condition.

Here all three identical resistors are in parallel, so equivalent resistance is, $R_{e q} = \frac{12}{3} = 4 Ω$

Now, current through the battery is $I = \frac{12}{4} = 3 A$
