When current in coil is uniformely reduced from 2A to 1A in 1 ms , the induced emf is 5V. The inductance of coil is :

The current in a coil changes from 0 to 20 A in 0.5S. If the induced emf is 80V, the 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.

When a current changes from 2A to 4A in 0.05 sec . In a coil , induced emf is 8 V . The self inductance of 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

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
