Switch S of the circuit shows in Fig is ...

Switch `S` of the circuit shows in Fig is closed at `t = 0`. If `e` denotes the induced emf in `L` and `I` is the current flowing through the circuit at time `t`, which of the following graphs is//are correct?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
At t = 0, induced emf e is maximum and is equal to applied emf, but curent `i` is zero.
After lapse of time, current through the circuit increases but induced emf decreases.
