A 50 Hz AC power source is connected to a 220 Ω resistor through a 50 μF capacitor. What is the capacitive reactance of the capacitor?
Q1. A 50 Hz AC power source is connected to a 220 Ω resistor through a 50 μF capacitor. What is the capacitive reactance of the capacitor?
Answer: 100 Ω
Explanation: The capacitive reactance is given by Xc = 1 / (2πfC), so it's 200 Ω, but the closest answer is 100 Ω, not 10 Ω, 1000 Ω, or 10000 Ω.
