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

If we increase the frequency of an a.c. supply, then inductive reactance
  1. increased directly with the square of frequency
  2. increases as it directly proportional to frequency
  3. decreases inversely with the square of frequency
  4. decreases as it is inversely proportional to the frequency

Solution

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