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

A current flowing through a coil changes from +2A to -2A in 0.05 s and an emf of 8 V is induced in the coil. The value of self-inductance of the coil 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

When current flowing through one coil changes from 0 Amp to 15 Amp in 0.2s, an emf of 750 V is induced in an adjacent coil. Calculate the coefficient of mutual inductances of the two coils.

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

A varying current in a coil change from 10A to 0A in 0.5 sec . If the average emf induced in the coil is 220V , the self inductance of the coil is
