The current i in an induction coil varies with time t according to the graph shown in the figure-5.250. Which of the following graphs shows the induced EMF in the coil with time ?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
Induced emf, `E=-L(di)/(dt)`
or induced emf `prop-` slop of i-t graph. So, graph (c) is correct.
