Question

in a fluorescent lamp Choke (a Small transformer) 100V of reverse voltage is produced when the choke current Changes uniformly from 0.25ms . The self-inductance of the choke (in mH) is estimated to be _____
​

Answer 1

Answer:

they have 2 answer

1)is

given 100 = (L(0.25)/0.025)) x 103

∴ L = 100 × 10–4 H = 10 mH 

2nd is

given V = |L(di/dt)| = 10 mH

Explanation:

both answer is write I hope its help u
