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

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 5 is closed current through L is zero and it acts as open circuit.   \[{{i}_{1}}=0\]    SO, \[{{i}_{2}}>{{i}_{3}}>{{i}_{1}}\] \[i_{3}^{0}=\frac{E}{2R}\]
