JEE Main 2023 — Alternating Current Question with Solution

JEE Main 2023 (24 Jan Shift 2)

Question

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
3

Step-by-step explanation

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, Req=123=4 Ω

Now, current through the battery is I=124=3 A
