Define self inductance of a coil.

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.

When an ac signal of frequency 1200 Hz is applied to a coil of reactance 120Omega , the applied voltage leads the current by 45^@ .Calculate the 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 :

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?

The current in a coil at time t is I = t^2e^(-t) . The self inductance of the coil is L= 2mH . How much time it will take to e.m.f. be zero?

Statement I: Self-inductance of a solenoid having 1000 turns is 100 mH if the associated magnetic flux linked with each turn is 10^(-3) Wb for a current of 1 A passig through the solenoid. Statement II: The self-inductance L of a coil is defined as phi=LI when phi is the magnetic flux linked with the coil for a current I through it.

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.

Statement I: When the number of turns of a coils is doubled, coefficient of self-inductance of the coil becomes 4 times. Statement II: Self-inductance prop ("number of turns")^(2)

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.

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
