A current I =10 (100 t ) ampere, is passed in coil which induces a maximum emf 5 volt in neighboring coil. The mutual inductance of two coils is

Options

  1. A5mH
  2. B10mH
  3. C15mH
  4. D25mH

Correct answer

A. 5mH

Step-by-step solution

Induced emf e = M dI dt = M 1000 (100 t ) The maximum value of emf, e ₀=1000 M M = 5 1000 =5 mH
