Q. Induced emf in the coil depends upon :
UPSEE
UPSEE 2006
A
conductivity of coil
B
amount of flux
C
rate of change of linked flux
D
resistance of coil
Solution:
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., $e =\frac{d\phi_{B}}{dt}$
Hence, induced emf in a coil depends on rate of change of flux.
