With unity coupling, the mutual inductance will be(a) L1 x L2(b) L1/L2(c) √(L1 x L2)(d) L2/L1The question was asked in an interview.My question is based upon Inductances topic in chapter Magnetic Forces and Materials of Electromagnetic Theory

Answer» CORRECT answer is (c) √(L1 x L2)

Easy EXPLANATION: The expression for MUTUAL inductance is given by M = K √(L1 x L2),where k is the coefficient of coupling. For unity coupling, k = 1, then M = √(L1 x L2).
