If reversible voltage of 200 V is applied across an inductor, current in it reduces from 0.25A to 0A in 0.025 ms. Find inductance of inductor (in mH).

In a fluorscent lamp choke (a small transformer) 100V of reverse voltage is produced when the choke current changes uniformly from 0.25 A to 0 in a duration of 0.025 ms. The self-inductance of the choke (in mH) is estimated to be……………..

In a fluorscent lamp coke (a small transformer) 100V of reverse voltage is produced when the choke current changes uniformly from 0.25 A to 0 in a duration of 0.025 ms. The self-inductance of the choke (in mH) is estimated to be……………..

Current in an inductance of 1 mH is reduced from 5A to 0 in 1 ms. The emf induced in it is (in V)

An average emf of 25 V is induced in an inductor when the current in it is changed from 2.5 A in one direction ot the same value in the opposite direction in 0.1s. Find the self-inductance of the inductor.

An average emf of 20 V is induced in an inductor when the current in it is changed from 2.5 A in one direction to the same valute in the opposite direction in 0.1 s. Find the self inductance of the inductor.
