Q. 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
Explanation
(c) According to Faraday’s law, “the induced emf in a closed loop equals the time rate of change of magnetic flux through the loop.”
$ie.,\ $ $e = - \frac{d\phi_{B}\ }{dt}$
Hence, induced emf in a coil depends on rate of change of flux.
