Question

# The current i in an induction coil varies with time t according to the graph shown

in figure. Which of the following graphs shows the induced emf (e) in the coil with time

## The correct answer is:

### Emf induces during ‘a’ = 0

emf induced during ‘b’ is constant throughout emf induced during ‘c’ is constant throughout magnitude of emf induced during ‘b’ is equal to the magnitude of emf induced during ‘c’. But the direction opposite
