Three identical resistors with resistance R = 12Ω and two identical inductors with self 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 b $e________A.$

Question

G1 Physics · Accepted Answer

Long after the switch is closed, ideal inductors behave as short circuits. The network reduces to three 12 Ω resistors in parallel, so equivalent resistance is R/3 = 4 Ω. Therefore battery current is I = 12/4 = 3 A.
