Two coils A and B have mutual inductance 0.008 H . The current changes in the coil A , according to the equation I = I _ m t , where I_m=5 A and =200 rad s ⁻¹ . The maximum value of the e.m.f. induced in the coil B in volt is
Options
- A4
- B8
- C10
- D16
Correct answer
B. 8
Step-by-step solution
e = M dI dt Given: M =0.008, I _ m =5 ~A , =200 rad / s e =0.008 I _ m e os t For e = e _ , t =1 aligned e _ & =0.008 I _ m & =0.008 5 200 & =8 aligned
