Alternating Current

Question

Wired Faculty App

Induced emf in the coil depends upon

conductivity of coil

amount of flux

rate of change of linked flux

resistance of coil

Solution

C.

rate of change of linked flux

According to Faraday's law, "the induced emf in a closed loop equals the time rate of change of magnetic flux through the loop".

i.e $e = - \frac{{dϕ}_{B}}{dt}$

Hence, induced emf in a coil depends on the rate of change of flux.
