The coefficient of mutual inductance between a pair of coils is 5mH. Find the e.m.f.induced in one coil when the current in the other coil changes at the rate of `250A//s`.

To induce an e.m.f. in the coil

The mutual inductance of a pair of coils is 0.75H. If the current in the primary coil changes from 0.5A to zero in 0.01s, find the average induced e.m.f. in the secondary.

An emf of 96.0 mV is induced in the windings of a coil when the current in a nearby coil is increasing at the rate of 1.20 A/s . What is the mutual inductance (M) of the two coils ?

Two coils are connected in series in one gap of the meterbridge and null point is obtained of the middle of the wire by putting 75Omega in the other gap. Two coils are then connected in parallel and the null point is obtained again at the middle of the wire when the resistance in the other gap is changed by 57Omega . Find the resistance of each coil.
