When a current of 2 ~A is passed through a coil of 100 turns, flux associated with it is 5 10⁻⁵ ~Wb . Find the self inductance of the coil.
Options
- A4 10⁻³ H
- B4 10⁻² H
- C2.5 10⁻³ H
- D10⁻³ H
Correct answer
C. 2.5 10⁻³ H
Step-by-step solution
Self inductance, L= N i array l = 100 5 10⁻⁵ 2 =250 10⁻⁵ =2.5 10⁻³ H array
