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 in flux linkage with the other coil?

Text Solution

Verified by Experts

Here, `M = 1.5 H, (dI)/(dt) = (20 - 0)/(0.5) = 40 As^(-1)`
From `e = M (dI)/(dt) = (d phi)/(dt) , d phi = M dI = 1.5 (20 - 0) = 30 Wb`
