The inductive reactance of a coil is ' R ' . If inductance of a coil is tripled and frequency of a.c supply is also tripled, then new inductive reactance will be

Options

  1. AR 9
  2. BR 3
  3. C3 R
  4. D9 R

Correct answer

D. 9 R

Step-by-step solution

Inductive reactance = X _ L = R =2 fL If L and f both are tripled, the inductive reactance will become 9 R .
