If the current in the primary circuit of a pair of coils changes from 10 A to 0 in 0.1 s, calculate (i) the induced emf in the secondary if the mutual inductance between the two coils is 2 H and (ii) the change of flux per turn in the secondary if it has 500 turns.

If the current in the primary circuit of a pair of coils changes from 5 A to 1 A in 0.02 s. Calculate (i) induced emf in the secondary coil if the mutal inductance between the two coills is 0.5 H and (ii) the change of flux per turn in the secondary ,if it has 200 turns .

If the current in the primary circuit of a pair of coils changes from 5 amp to 1 amp in 0.02 sec, calculate (i) induced emf in the secondary coil if the mutual inductance between the two coils is 0.5H and (ii) the change of flux per turn in the secondary, if it has 200 turns.

If the current in the primary coil is reduced from 3 A to zero in 0.001 s, the induced emf in the secondary coil is 1500 volt. Calculate the mutual inductance between two coils.

If a current of 3 A flowing in the primary coil is reduced to zero in 0.01 s, the e.m.f induced in the secondary coil is 750 V. What is the mutual inductance between the two coil ?

The current in a primary coil increases by 20 A in 0.1 s. If the average emf induced in the secondary coil be 100 V, determine the mutual inductance between the coils and the change in magnetic flux in the secondary coil.

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

When the primary current in the spark-coil of a car changes from 4A to zero in 10muS , an emf of 40,000 V is induced in the secondary. The mutual inductance between the primary and the secondary windings of the spark-coil will be -
