What is the self inductance of a coil in which an induced emf of 2 ~V is set up, when the current is changing at the rate of 4 As ⁻¹

Options

  1. A0.5 mH
  2. B0.05 H
  3. C2 H
  4. D0.5 H

Correct answer

D. 0.5 H

Step-by-step solution

Induced emf, e= L d i d t , here, e=2 ~V , d i d t =4 As ⁻¹ aligned & 2=L 4 L &= 2 4 =0.5 H aligned
