Find the e.m.f induced in a 1 mH inductor through which the current decreases from 20 A to 10 A in 10 milli seconds.

Two adjacent coils have a mutual inductance of 200 mH. Find the emf induced in the secondary when the current through the primary is increased from 0 to 10 ampere in 10 millisecond.

The emf induced in a coil is -2 volt by changing the current form 8 miliampere to 6 milliampere in 2 xx 10^-3 second. The self inductane of the coil in henry is

The current through a 1mH inductor changes from 5 ampere to 10 ampere in 1 millisecond. Find the emf induced.

A pair of adjacent coils X and Y has a mutual inductance of 1.5 mH. If the current in the coil X changes from 0 to 10 A in 0.04 s, then calculate the average induced e.m.f in the coil Y. If the coil Y has 100 turns, then find the rate of change of flux through each turn of this coil
