A pair of adjacent coils has a mutual inductance of 1.5 H. If the current in one coil changes from 0 to 20 A in 0.5 s, what is the change of flux linkage with the other coil?

Text Solution

Verified by Experts

Given, `M=1.5H,DeltaI_(1)=20A,Deltat=0.5s`
`therefore` Change of flux linkage with the other coil,
`Deltaphi_(2)=MDeltaI_(1)=1.5xx20=30Wb`
