Solution


Q.

Three identical resistors with resistance R=12 Ω 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 be ________ A.                  [2023]

Ans.

(3)

After long time an inductor behaves as a resistance-less path. So current through cell

I=12R/3=3 A    {∵R=12 Ω}
