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

Two neighbouring coils A and B have a mutual inductance of 20 mH. The current flowing through A is given by i=3t^(2)-4t+6 . The induced emf at t = 2s is

Two coils have mutual inductance of 1.5 henry. If current in primary circuit is raised to 5 ampere in one millisecond after closing the circuit, what is the e.m.f. Induced in the secondary ?

Two coaxial coils are very close to each other and their mutual inductance is 10 mH. If a current (60 A) sin 500t is passed in one of the coils, then find the peak value of induced emf in the secondary coil.

The mutual inductance between two coils is 1.25 henry. If the current in the primary changes at the rate of 80 ampere//second , then the induced e.m.f. in the secondary is
