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.
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 of a capacitor is given by the formula:
where is the capacitance and is the frequency of the AC source.
From the formula, it is clear that is inversely proportional to the capacitance . Therefore, as capacitance increases, the capacitive reactance decreases. This makes Statement I incorrect.
Also, is inversely proportional to the source frequency . Therefore, the capacitive reactance depends on the source frequency. This makes Statement II incorrect.
Hence, both Statements I and II are incorrect.
