Two coils X and Y are placed in a circuit such that a current changes by 3 A in coil X and magnetic flux changes of 1.2 Wb occurs in Y . The value of mutual inductance of the coils is

Options

  1. A0.2 H
  2. B0.4 H
  3. C0.6 H
  4. D3.6 H

Correct answer

B. 0.4 H

Step-by-step solution

Given, d =1.2W b, M=?d I=3 ~A As, =M I d =M d I M= d d I = 1.2 3 =0.4 H
