Two coils A and B are placed in a circuit. When current in the coil A changes by 0.8 ~A the magnetic flux in coil B changes by 0.16 ~Wb . The mutual inductance between the coils is
Options
- A2 H
- B20 H
- C0.5 H
- D0.2 H
Correct answer
D. 0.2 H
Step-by-step solution
The magnetic flux in coil B is given by, =M i₁ where, M is the coefficient of mutual inductance, i₁ is the current in coil A. M= i₁ = 0.16 ~Wb 0.8 ~A =0.2 H
