The mutual inductance between a pair of coils each of `'N'` turns is `'M'`. If a current is `'I'` in the first coil is brought to zero in a time `t`, then the avergae emf induced in the second coil is

The mutual inductance of a pair of coils, each of N turns, is M henry. If a current of I ampere in one of the coils is brought to zero in t second, the emf induced per turn in the other coil, in volt, will be

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.

Two coils have a mutual inductance of 0.01 H. The current in the first coil changes according to equation, I = 5 sin 200 pi t. The maximum value of emf induced in the second coil is

Current in a coil changes from 4 A to zero in 0.1 second and the emf induced is 100 V. The self inductance of the coil is

Current in a coil changes from 4 A to zero in 0.1 second and the emf induced is 100 V. The self inductance of the coil is

The coefficient of mutual induction between two coils is 4H . If the current in the primary reduces from 5A to zero in 10^(-3) second, then the induced e.m.f. in the secondary coil will be
