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

  1. AStatements I and II are incorrect.
  2. BStatement I is correct; Statement II is incorrect.
  3. CStatements I and II are correct.
  4. DStatement I is incorrect; Statement II is correct.

Correct answer

A. Statements I and II are incorrect.

Step-by-step solution

The capacitive reactance XCX_C of a capacitor is given by the formula:

XC=1ωC=12πfCX_C = \dfrac{1}{\omega C} = \dfrac{1}{2\pi f C}

where CC is the capacitance and ff is the frequency of the AC source.

From the formula, it is clear that XCX_C is inversely proportional to the capacitance CC. Therefore, as capacitance increases, the capacitive reactance decreases. This makes Statement I incorrect.

Also, XCX_C is inversely proportional to the source frequency ff. Therefore, the capacitive reactance depends on the source frequency. This makes Statement II incorrect.

Hence, both Statements I and II are incorrect.

Answer: Statements I and II are incorrect.
