हिन्दीCalculate the capacitive reactance of a \( 10\text{ }\mu\text{F} \) capacitor connected to a \( 50\text{ Hz} \) ac source (use \( \pi = 3.14 \)):
View Answer & Solution
Correct answer · Option D
\( 318\text{ }\Omega \)
Explanation
Capacitive reactance \( X_c = \frac{1}{2\pi f C} = \frac{1}{2 \times 3.14 \times 50 \times 10 \times 10^{-6}} \approx 318\text{ }\Omega \).
