Question

A current in a coil changes from 2.5 A to 0 A in 0.1 s inducing an emf

of 200 V. Calculate the value of self inductance.​

Answer 1

Answer:

of 200 v. calculate the value of self inductance

Answer 2

Answer:

ANSWER

Rate of change of current dtdi=0.10.0−2.5

⟹ dtdi=−25 A/s

Induced emf E=200V

Using E=−Ldtdi

∴ 200=−L×(−25)

⟹ L=8H
