Solution

The correct option is C

Rate of change of linked flux


Explanation:

The rate of change of connected flux determines the induced emf in the coil which is e=-dΦdt.

Where,

e=Induced emf

-dΦ= Changing flux

dt=Time

Therefore, from the equation e=-dΦdt, it is clear that induced emf depends upon the rate of change linked to flux.

Hence, option (C) is correct.
