Question

Induced emf in the coil depends upon

• A. Conductivity of coil
• B. Amount of flux
• C. Rate of change of linked flux
• D. Resistance of coil

Answer 1

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 $e=\frac{-d\Phi }{dt}$.

Where,

$e=$Induced emf

$-d\Phi =$ Changing flux

$dt=$Time

Therefore, from the equation $e=\frac{-d\Phi }{dt}$, it is clear that induced emf depends upon the rate of change linked to flux.

Hence, option (C) is correct.
