Question:

In the figure shown, a circuit contains two identical resistors with resistance R = 5Ω and an inductance with L = 2mH. An ideal battery of 15V is connected in the circuit. What will be the current through the battery long after the switch is closed?

5.5A

7.5A

The correct option is A (6A)

Ideal inductor will behave like zero resistance long time after switch is closed.
I = V/R = 2 × 15/5 = 6A
