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` the current flowing through the circuit at time `t`, then which of the following graphs correctly represents the variation of `e` with `i`?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
At the time `t=0`, `e` is max and is equal to `E`, but current `i` is zero .
As the time passes, current through the circuit increase but induced elf decreases.
