A pair of coils of turns 
and 
are kept close together. Current passing through the first is reduced at the rate 
and emf 3 mV is developed across the other coil. If the second coil carries current which is then reduced at the rate 
, then the emf produced across the first coil will be
A
B
C
6 mV
D
Text Solution
Verified by ExpertsThe correct answer is:
C
, when rate of change of current is doubled, induced emf also becomes two times.
Thus, emf produced across the first coil is 6 mV.
