In shown circuit switch is closed at t = 0.

Assertion : At t = 0, current through battery $I = \frac{E}{2 R}$ and at $t = \infty$ , current through battery will be $I = \frac{E}{R} .$
Reason : At $t = 0,$ inductor will behave like open circuit and at $t = \infty,$ inductor will behave like short circuit.
