The self-inductances of two identical coils are 0.1H. They are wound over each other. Mutual inductance will be-

The self inductances of two coils are 16 mH and 25 mH, and they have a mutual inductances of 10 mH. Their coupling constant is

The sum and difference of self-inductances of two coils are 13 mH and 5 mH respectively. What is the maximum value of mutual inductance (in milli henry) of the two coil ?

Two coils of self inductance 1 H and 3H are connected in series to support each other. Their mutual inductance is 6H. What is the self inductance of the combination ?

What is meant by 'self-inductance of coil is 1 H '?

The coefficients of self induction of two coils are respectively 2 mH and 3 mH. They are coupled so as to oppose each other. What will be their self inductance if their mutual inductance is 1 mH?

If two coil are wound on a soft iron core the mutual induction is

Two coils of self inductance 100 mH and 400 mH are placed very closed to each other. Find maximum mutual inductance between the two when 4 A current passes through them.
