Two coils of self-inductance 25 mH and 9 mH are placed close together such that the effective flux in one coil is completely linked with the other. The mutual inductance between these coils is

Options

  1. A34 mH
  2. B16 mH
  3. C15 mH
  4. D6 mH

Correct answer

C. 15 mH

Step-by-step solution

If L ₁ and L ₂ are the inductances of the first and second coil respectively, then mutual inductance between the two coils is given by M = L ₁ ~L ₂ = 25 9 =15 mH
