A current I=20sin(100pit)A is passed in the first coil, which induces a maximum emf of 10piV in the second coil. The mutual inductance for the pair of coils is

When a current i = 10 sin (100 pi t) A is passed through a coil, an induced emf having a maximum value of 5 pi V is produced in a nearby coil kept parallel to the first coil. What is the mutual inductance between the two coils?

If the current 30A flowing in the primary coil is made zero in 0.1 sec. the emf induced in the secondary coil is 1.5 volt. The mutual inductance between the coil is

If a current of 3A, flowing in the primary coil is reduced to zero in 10^(-3) s , the induced e.m.f in the secondary coil is 15000 V. The mutual inductance between the 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 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

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
