Energy needed to establish an alternating current I in a coil of self inductance L is

The unit of self inductance of a coil is

A magnetic flux of 8X10^(-4) weber is linked with each turn of a 200 - turn coil when thereis an electric current of 4 A in it. Calculate the self inductance of the coil.

The coefficient of self inductance of a coil is

A magnetic flux of 9 xx 10^(-4) weber is linked with each turn of a 200 turn coil when there is an electric current of 3 A in it. The self inductance of the coil is

The currents flowing in the two coils of self - inductance L_(1)= 20 m H and L_(2) = 15 mH are increasing at the same rate. If the the power supplied to the two coils is equal find the ratio of (i) induced voltages (ii) the currents and (iii) the energies stored in the two coils at a given instant.

The current flowing in a coil of self-inductance 0.4 mH is increased by 250mA in 0.1 sec. the e.m.f. induced will be

Magnetic flux of 5 microweber is linked with a coil when a current of 1 mA flows through it. What is self inductance of the coil ?
