If we increase the frequency of an a.c. supply, then inductive reactance

  • A
    increased directly with the square of frequency
  • Correct answer
    B
    increases as it directly proportional to frequency
  • C
    decreases inversely with the square of frequency
  • D
    decreases as it is inversely proportional to the frequency

Solution

Inductive reactance $\mathrm{X}_{\mathrm{L}}=2 \pi \mathrm{fL}$ $\therefore \mathrm{X}_{\mathrm{L}} \propto \mathrm{f}$

Hence, the correct answer is option: 'B'.
