A coil of 200 turns carries a current of o.4 A. If the magnetic flux of 4 m Wb is linked with the coil, find the inductance of the coil.

Text Solution

Verified by Experts

Given : No. of turns N = 200
Current flowing through coil I = 0.4 A
Magnetic flux linked with coil `Phi`
`=4mWb=4xx10^(-3)Wb`
To find :
Inductance of the coil L = ?
`NPhi=LI`
Solution :
`thereforeL=(NPhi)/(I)=(200xx4xx10^(-3))/(0.4)`
`=(800xx10^(-3))/(0.4)=2H`
L = 2 H
