ElectroMagnetic InductionHard

Question

In the given circuit find the ratio of i1 to i2. Where i1 is the initial (at t = 0) current, and i2 is steady state
(at t = ∞) current through the battery :

Options

A.1.0
B.0.8
C.1.2
D.1.5

Solution

Initially the inductor offers infinite resistance hence i1 is 1A. Finally, at steady state inductor offers zero resistance and current  i2 is 1.25 A in the battery.
