Problem 10: 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 linking with other coil?

Solution

Given     Mutual inductance, M= 1.5 H,      Time, Δ t = 0.5 s

               Initial current = 0,             Final current = 20 A

Find        Change in flux linking with other coil, Δϕ

Formula               Since

Put the values
