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 .

Correct answer

0

Step-by-step solution

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 = 12 3 = 4   Ω Now, current through the battery is I = 12 4 = 3   A
