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

A current through a coil of self inductance 10 mH increases from 0 to 1 A in 0.1 s. What is the induced emf in the coil?

The current in a self-inductance L = 40 mH is to be increased uniformly from 1 A to 11 A in 4 millisecond. The e.m.f. induced in the inductor during to process is

The current in coil of self inductance 5 mH changes from 2.5 A to 2.0 A is 0.01 second. Calculate the value of self induced e.m.f.

The current in a self inductance L = 40 mH is to be increased uniformly from 1A to 11A in 4 ms. The e.m.f. induced in inductor during this process is

The current through a coil of inductance 5 mH is reversed from 5A to -5A in 0.01 s. What is the maximum self-induced emf in the coil?

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
