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

Text Solution

Verified by Experts

Here `(d phi)/(dt)=8xx10^(-4) weber, n=200,i=4A`
`or L=(n/i)(d phi)/(dt)`
`=200xx8xx10^(-4)`
`=4xx10^(-2)H.`
