When the current in a coil changes from 2 A to 4 A in 0.05 s, an e.m.f. of 8 V is induced in the coil. The coefficient of self-induction of the coil is

Figure shows a short solenoid of length 4 cm, radius 2.0 cm and number of turns 100., lying inside on the axis of a long solenoid, 80 cm long and number of turns 1,500. What is the flux through the long solenoid, if a current of 5.0 A flows through the short solenoid? Also obtain the mutual inductance of the two solenoids.

When the current changes fro +2A to -2A in 0.05 s, an e.m.f. of 8 V is induced in the coil. The coefficient of self-indution of the coil is

An e.m.f. of 250 muV is induced in a coil, when current in it changes from 10 A to 6 A in 0.4 s. What is the self inductance of the coil?

Current in a circuit falls from 5.0 A to 0.0 A in 0.1 s. If an average emf of 200 V induced, give an estimate of the self-inductance of the circuit.

In a coil of self-induction 5 H, the rate of change of current is 2 A s^-1 . Then, e.m.f. induced in the coil is

Whenever changing current is passed through a conductor, an e.m.f. is induced, that is.
