The resistance offered by the inductor $\left(X_L\right)$ in an ac circuit is

The resistance offered by the inductor $\left(X_L\right)$ in an ac circuit is
  1. inversely proportional to inductance and directly proportional to the frequency of alternating current
  2. inversely proportional to inductance and frequency of the alternating current
  3. directly proportional to inductance and frequency of alternating current
  4. inversely proportional to frequency of alternating current and directly proportional to inductance.

Solution

The expression for inductive reactance is: $X_{\mathrm{L}}=2 \pi f L$ Therefore, $X_{\mathrm{L}} \propto L$ and $X_{\mathrm{L}} \propto f$.
