If a change in current of 0.01 ~A in one coil produces a change in magnetic flux of 2 10⁻² Wb in the other coil, then the mutual inductance of the two coils in henry is
Options
- Azero
- B10 ~T
- C20 ~T
- D200 ~T
Correct answer
C. 20 ~T
Step-by-step solution
aligned & i=0.01 ~A , =2 10⁻² ~Wb & Mutual inductance M= i & = 2 10⁻² 0.01 = 2 10⁻² 10⁻³ & =2 H aligned
