When a current of 1 ~A is passed through a coil of 100 turns, the flux associated with it is 2.5 10⁻⁵ ~Wb / turn. The self inductance of the coil in millihenry is

Options

  1. A40
  2. B25
  3. C4
  4. D2.5

Correct answer

D. 2.5

Step-by-step solution

Given: N=100, I=1 ~A , =2.5 10⁻⁵ ~Wb / turn Self-inductance of coil, aligned L & = N I L & = 100 2.5 10⁻⁵ 1 =2.5 10⁻³ H =2.5 mH aligned
