A magnetic flux of `8xx10^(-4)` weber is linked with each turn of a 200 - turn coil when thereis an electric current of 4 A in it. Calculate the self inductance of the coil.

Text Solution

Verified by Experts

`"Total flux linked "phi=200xx8xx10^(-4)=0.16" weber"`
`"Now inductance L"=(phi)/(i)=(0.16)/(4)=0.04-40mH`
