Three identical resistors with resistance R=12ΩR = 12Ω and two identical inductors with sell inductance L=5mHL = 5mH are connected to an ideal battery with emf of 12V12V as shown in figure. The current through the battery long after the switch has been closed will be________AA.

Three identical resistors with resistance R = 12Ω and two identical inductors with sell inductance L = 5mH are

Correct answer

0

Step-by-step solution

Three identical resistors with resistance R = 12Ω and two identical inductors with sell inductance L = 5mH are

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=4Ω{R}_{eq} = \dfrac{12}{3} = 4Ω

Now, current through the battery is I=124=3AI = \dfrac{12}{4} = 3A
