Self inductances of two uncoupled coils are 40 and 90 mH. Their mutual inductance is??
Dear student,
The coefficient of coupling is given as K = M/√(L1L2); where M is the mutual inductance, L1 and L2 are the self-inductances respectively So, for calculating the mutual inductance we need to know the coefficient of coupling K which is not provided in the question so post the question again so that we can help you ASAP.
Regards
