Question

The current flowing through the circuit at t = 0 in the circuit shown below is?

(a) 1

(b) 2

(c) 3

(d) 0

This question was posed to me in examination.

The origin of the question is Sinusoidal Response of an R-L Circuit in chapter Transients of Network Theory

Answer 1

Right answer is (d) 0

The best I can explain: At t = 0 that is initially the current flowing through the circuit is zero that is i = 0. So, i = 0.
