NEET2002PhysicsElectromagnetic InductionActual
The coefficient of mutual inductance, when magnetic flux changes by 2 10⁻² ~Wb and current changes by 0.01 ~A is
Options
- A2 H
- B4 H
- C3 H
- 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).
