⚠️ Common Exam Traps & Conceptual Pitfalls

Students often incorrectly assume that increasing frequency increases the reactance of all components; however, capacitive reactance $X_C = \frac{1}{\omega C}$ is inversely proportional to frequency, so it decreases as frequency rises, while only inductive reactance $X_L = \omega L$ increases.

An inductor, a resistance and a capacitor are joined in series with an AC source. As the frequency of the source is slightly increased from a very low value, the reactance

Multiple Choice Options

  • A of the inductor increases
  • B of the resistor increases
  • C of the capacitor increases
  • D of the circuit increases

Step-by-Step Verified Solution

**Answer:** (a) of the inductor increases. **Step-by-Step Explanation:** Inductive reactance X_L = _L increases with frequency.
