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 ?

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

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

Two coils A and B have mutual inductance 2xx10^(2) henry if the current in he primary is i=5 sin 10^(pi) t then the maximum value of emf induced in coil B is

Two coils P and S have a mutual inductance of 5 xx 10^(-3)H . If the current in the primary is I=10 sin(100 pi t) , then the maximum value of the e.m.f. induced in S is

Two coaxial coils are very close to each other and their mutual inductance is 5 mH. If a current (50 A) sin 500t is passed in one of the coils, then find the peak value of induced emf in the secondary coil.
