In which of the following circuit is the current maximum just after the switch S is closed?

(i)

(ii)

(iii)

A)  (i)                          

B)  (ii)

C)  (iii)                        

D)                                         Both (ii) and (iii)

Correct Answer: B

Solution :

The inductor (L) will not work on DC so as the switch S is closed current through L is zero and it acts as open circuit. So, \[{{i}_{2}}>{{i}_{3}}>{{i}_{1}}\]            \[i_{3}^{0}=\frac{E}{2R}\]
