A varying current at the rate of `3A//s` in a coil generates an e.m.f. of `8mV` in a nearby coil. The mutual inductance of the two coils is

If the rate of change of current is 1A per second in one coil induces an emf of 2 V in the neighbouring coil, the mutual inductance of two coils is

If the rate of change of current of 1A/s in one coil, induced an emf of 1 V in the neighbouring coil, the mutual inductance of two coils is

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

The current in a coil is changed from 5A to 10 A in 10^(-2) s . An emf of 50 mV is induced in coil near by it. The mutual inductance of two coils is

The current decays from 5A to 2A in 0.01 s in a coil. The emf induced in a coil nearby it is 30V . The mutual inductance between the coils is

If the current in the primary coil is reduced from 3.0 ampere to zero in 0.001 second, the induced e.m.f in the secondary coil is 1500 volt. The mutual inductance of the two coils will be-
