Question

In the circuit shown in the figure, E = 15 V , R 1 = 1 Ω , R 2 = 1 Ω , R 3 = 2 Ω and L = 1 . 5 H . The currents flowing through R 1 , R 2 and R 3 are i 1 , i 2 and i 3 , respectively. Immediately after connecting switch S w ,, i 3 = 0 A and d i 3 d t = 0 A s - 1, i 3 = 0 A and d i 3 d t ≠ 0 A s - 1, i 3 = 0 A , and rate at which magnetic energy stored is not zero, None of these

At t = 0 , circuit can be considered as follows. After a long time, circuit can be considered as follows. The current i 3 is zero at the instant of closing the switch but with time it grows and achieves a non-zero value, hence d i 3 d t ≠ 0
