NEET Physics AC Voltage MCQ Question
A capacitor with a capacitance of 10 μF is connected to an AC source with a frequency of 50 Hz. What is the capacitive reactance of the capacitor?
318 Ω
159 Ω
636 Ω
79.5 Ω
Correct Answer
Detailed Explanation
Using the formula for capacitive reactance Xc = 1/(ωC), where ω = 2πf, we calculate Xc = 1/(2π × 50 × 10 × 10⁻⁶) = 318 Ω.
