If a current of `10 A` flows in one second through a coil and the induced e.m.f. is `10V`, then the self-inductance of the coil is

If a current of 10 A changes in one second through a coil, and the induced emf is 20 V, then the self-inductance of the coil is

If a current of 10 A changes in one second throught a coil, and the induced emf is 10 V, then the self-inductance of the coil is

The current in the coil changes from 3A to 6 A in 3sec. If the induced e.m.f. in the coil is 60 V, then self inductance of the coil is

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.

The current in a coil changes from 0 to 2 A in 0.05 sec. If the induced e.m.f is 80 V, the self inductance of the coil is

The current in a coil decreases from 5 A to 0 in 0.1 sec. If the average e.m.f induced in the coil is 50 V, then the self inductance of the coil is

Current in a coil changes from 4 A to zero in 0.1 second and the emf induced is 100 V. The self inductance of the coil is
