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?
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
Put the values
