Consider the statements on capacitive reactance. Statement I: As capacitance increases, the capacitive reactance also increases. Statement II: The capacitive reactance is independent of the source frequency.
Options
- AStatements I and II are incorrect.
- BStatement I is correct; Statement II is incorrect.
- CStatements I and II are correct.
- DStatement I is incorrect; Statement II is correct.
Correct answer
A. Statements I and II are incorrect.
Step-by-step solution
The capacitive reactance X_C of a capacitor is given by the formula: X_C = 1 C = 1 2 f C where C is the capacitance and f is the frequency of the AC source. From the formula, it is clear that X_C is inversely proportional to the capacitance C . Therefore, as capacitance increases, the capacitive reactance decreases. This makes Statement I incorrect. Also, X_C is inversely proportional to the source frequency f . Therefore, the capacitive reactance depends on the source frequency. This makes Statement II incorrect.
