Question

In the circuit shown below, the key K is closed at t = 0 . The current through the battery is, 5 A at t = 0 and 7 A at t = ∞, 3 A at t = 0 and 1 A at t = ∞, 1 A at t = 0 and 3 A at t = ∞, 2 A at t = 0 and 6 A at t = ∞

MARKS App · Accepted Answer

At t = 0 , L behaves as open circuit and at t = ∞ as short circuit. So at t = 0 , i = 10 10 = 1 A [ ∵ R eq = 10 Ω ] and at t = ∞ , i = 10 10 3 = 3 A [ ∵ R eq = 10 3 Ω ]
