When the current in a coil changes form +2A to-2A in 0.5 sec then the induced e.m.f. is 8V, Find self inductance of the coil.

A varying current in a coil change from 10A to 0 in 0.5sec. If the average emf induced in the coil is 220V, the self inductance of the coil is :

A current flowing through a coil changes from +2A to -2A in 0.05 s and an emf of 8 V is induced in the coil. The value of self-inductance of the coil is

The mutual inductance between two adjacent coils is 1.5 H. If the current in the primary coil changes from 0 to 20 A in 0.05 s, determine the average emf induced in the secondary coil. If the number of turns in the secondary coil is 800, what change in flux will be observed in it?

An average induced emf of 0.20 V appears in a coil when the current in it is changed from 5A in one direction to 5A in the opposite direction in 0.20 s. Find the self-inductance of the coil in mH.

The current in a coil increases by 10 A in 0.01s. If the average emf induced in the coil is 100 V, find out the self-inductance of the coil and the flux linked with it.

For any inductive curcuit the induced current is reduced to zero from 10A in 0.1 sec time. If the value of induced emf be 100 mV.,then what will be the self inductance of the coil?

An emf of 100V is induced in a coil when the current through it changes at the rate of 50A.s^(-1) . Determine the self-inductance of the coil.
