The coefficient of mutual inductance of two coils is 6 mH. If the current flowing in one is 2A, the induced e.m.f. in the second coil will be
Options
(a) Zero
(b) 3 V
(c) 3 mV
(d) 2 mV
Correct Answer:
Zero
Explanation:
E.M.F. is induced in secondary coil only when current in primary coil changes. Since current in one coil is constant at 2 amp, e.m.f. induced in secondary coil is zero.
