The coefficient of mutual inductance, when magnetic flux changes by 2 10⁻² ~Wb and current changes by 0.01 ~A is

Options

  1. A2 H
  2. B4 H
  3. C3 H
  4. D8 H .

Correct answer

A. 2 H

Step-by-step solution

Change in magnetic flux ( )=2 10⁻² ~Wb and change in current (I)=0.01 ~A . Change in magnetic flux, =2 10⁻²=M I =M 0.01 or M= 2 10⁻² 0.01 =2 H (where M= coefficient of mutual inductance).
