A current of 10 A in primary of a circuit is reduced to zero at a unifrom rate in `10^(-3)`s. If coeff.of mutual inductance is 3 H, what is the induced e.m.f. in the secondary ?

A current of 10A in the primary of a circuit is reduced to zero at a uniform rate in 10^(-3) sec. If the coefficient of mutual inductance is 3 henry, what is the induced emf?

A current of 10A is reduced to zero at a uniform rate in 10^(-3)s . If co-efficient of mutual induction is 3H. What is the induced emf in the secondary?

A current of 0.5 A in the primary coil of a transfomer is reduced to zero at a uniform rate in 0.1 second. If the coefficient of mutual inductance is 3H, what is the emf induced in the secondary coil and charge in the magnetic flux per turn in the secondary coil if it has 50 turns?

A current 10 A in the primary of a transformer is reduced to zero at the uniform rate of 0.1 second. If the co-efficient of mutual inductance is 3H, what isthe e.m.f. induced in the secondary and change in the magnetic flux per turn in the secondary if it has 50 turns?

A current of 10A in the primary coil of a circuit is reduced to zero. If the coefficient of mutual inductance is 3 H and emf induced in the secondary coil is 30 kV, time taken for the change of current is

A current of 10A in the primary coil of a circuit is reduced to zero. If the coefficient of mutual inductance is 3 H and emf induced in the secondary coil is 30 kV, time taken for the change of current is

A current of 20 A in the primary part of a circuit is reduced to zero in 0.001 s. If the emf induced in the secondary part of tge circuit is 2000 V, then find the coefficient of mutual induction.
