The formula of capacitative reactance is
- A \(2 \pi f \mathrm{C}\)
- B \(\dfrac{f C}{2 \pi}\)
- C \(\dfrac{C}{2 \pi f}\)
- D \(\dfrac{1}{2 \pi f C}\)
Answer & Solution
Correct Answer
(D) \(\dfrac{1}{2 \pi f C}\)
Step-by-step Solution
Detailed explanation
The capacitive reactance \(X_{C}\) of a capacitor in an alternating current circuit is defined as the opposition offered by the capacitor to the flow of alternating current. The formula for capacitive reactance is given by \(X_{C} = \dfrac{1}{\omega C}\), where \(\omega\) is the…
