If a change in current of 0.01 ~A in one coil produces a change in magnetic flux of 2 10⁻² weber in another coil, then the mutual inductance between coils is
Options
- A0
- B0.5 H
- C2 H
- D3 H
Correct answer
C. 2 H
Step-by-step solution
Given, I=0.01 ~A =2 10⁻² ~Wb We know that, =M I where, M is mutual inductance between the coils. aligned & M= I &= 2 10⁻² 0.01 =2 H aligned
