The current in the primary coil of a transformer (assuming no power loss) as shown in fig. will be –

If the current in the primary coil is reduced from 3.0 ampere to zero in 0.001 second, the induced e.m.f in the secondary coil is 1500 volt. The mutual inductance of the two coils will be-

The number of turns in the primary coil of a transformer is 200 and the number of turns in the secondary coil is 1.0 if 240 volt AC is applied to the primary, the output from the secondary will be

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

When the current in a coil changeg from 8 amperes to 2 amperes in 3xx10^(-2) seconds, the e.m.f. induced in the coil is 2 volt. The self-inductance of the coil (in millihenry) is

With the decrease of current in the primary coil from 2 amperes to zero value in 0.01 s the emf generated in the secondary coil is 1000 volts. The mutual inductance of the two coils is

The current in the primary coil at time t is given by I=(8t^(2)-4) Ampere. If the e.m.f induced in the secondary coil is given by e_(s)=32 xx 10^(-3) t volt, then the mutual inductance between the two coil is
