USCG Exam PracticeAC circuits and theory
In an AC circuit, inductive reactance (XL) is calculated as XL = 2πfL. Which of the following statements correctly describes how inductive reactance changes with frequency?
- A. Inductive reactance decreases as frequency increases.
- B. Inductive reactance is independent of frequency.
- ✓ Inductive reactance increases as frequency increases.Correct
- D. Inductive reactance decreases as inductance increases.
Why C is correct
Per NEETS Mod. 2 §4-1, XL = 2πfL, so inductive reactance increases directly with frequency. Capacitive reactance behaves oppositely — it decreases with increasing frequency — making option A a plausible but incorrect distractor.
