Current in a circuit falls from 5.0 A to 0.0 A in 0.1 s. If an average emf of 200 V induced, give an estimate of the self-inductance of the circuit.

Text Solution

Verified by Experts

Average self induced emf is given by formula,
`lt epsilon gt =-L ((DeltaI)/(Deltat))`
`therefore 200=-L((0-5)/0.1)`
`therefore` L=4H
