In a coil of self-inuctance `0.5` henry, the current varies at a constant rate from zero to `10` amperes in `2` seconds. The e.m.f. generated in the coil is

A coil having an inductance of 0.5 H carries a current which is uniformly varying from zero to 10 ampere in 2 second. The e.m.f. (in volts) generated in the coil is

A coil having an inductance of 0.5 H carries a current which is uniformly varying from zero to 10 ampere in 2 second. The e.m.f. (in volts) generated in the coil is

The self-induced e.m.f in a 0.1H coil when the current in it is changing at the rate of 200 ampere//second is

The mutual inductance between two coils is 1.25 henry. If the current in the primary changes at the rate of 80 ampere//second , then the induced e.m.f. in the secondary is
