Two coils P and Q have mutual inductance 'M' H. If the current in the coil P is I = I₀ t , then the maximum value of e.m.f. induced in coil Q is

Options

  1. AMI₀
  2. BM I₀
  3. CM I₀
  4. DMI₀

Correct answer

C. M I₀

Step-by-step solution

The induced e.m.f. in coil Q due to the current in coil P is given by e = -M dI dt Given I = I₀ t , differentiating with respect to time t gives dI dt = I₀ t Substituting this into the expression for induced e.m.f., e = -M I₀ t The maximum value of the induced e.m.f. corresponds to the maximum magnitude of t , which is 1 . e_ max = M I₀
