The figure represents the voltage applied across a pure inductor. The diagram which correctly represents the variation of current `i` with time `t` is given by
.

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C

`V_L` function is cos function, which is `90^@` ahead of the current function. Hence, current function should be sin function.
