With increase of frequency of A.C supply, the inductive reactance is:
Correct answer: D. Increases as directly to frequency
- A. Decreases
- B. Increases as square of frequency
- C. Remain unchanged
- D. Increases as directly to frequency
Explanation
The correct option, "Increases as directly to frequency," means that as the frequency of an AC supply increases, the inductive reactance also increases proportionally. This relationship is linear, with inductive reactance directly proportional to the frequency of the AC signal.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
