When two inductors having the same value are connected in series with a small opposing mutual inductance (say the coefficient of coupling is 5 percent or so), the total reactance of the combination at a specific, constant frequency is (a) equal to the reactance of either inductor.
Slightly less than the reactance of either inductor
Slightly greater than the reactance of either inductor
Slightly less than twice the reactance of either inductor
Slightly greater than twice the reactance of either inductor
