Energy in a Coupled Electric Circuit | Wira Electrical
If the entire flux produced by one coil links another coil, then k = 1 and we have 100 percent coupling, or the coils are said to be perfectly coupled.Thus, The coupling coefficient k is a measure of the magnetic coupling between two coils; 0 ≤ k ≤ 1.For k < 0.5, coils are said to be loosely coupled; and for k > 0.5, they are said to be tightly coupled.
