In the circuit shows in Fig. switch `k_(2)` is open and switch `k_(1)` is closed at `t = 0`. At time `t = t_(0)`, switch `k_(1)` is opened and switch `k_(2)` is simultaneosuly closed. The variation of inductor current with time is

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
For `t lt t_(0), E = L(di)/(dt) rArr I = (E)/(L) t`
For `t gt t_(0), L(di)/(dt) = 0 rArr i =` constant
