Calculate the mutual inductance of two tightly coupled coils with inductances 49H and 9H.
Calculate the mutual inductance of two tightly coupled coils with inductances 49H and 9H. Correct Answer 21
For tightly coupled coils, the coefficient of coupling is unity. Then the mutual inductance will be M = √(L1 x L2)= √(49 x 9) = 21 units.
