A device is connected to a power source, and its impedance is measured to be 10 Ω. If the resistance is 5 Ω and the inductive reactance is 8 Ω, what is the capacitive reactance?
Q1. A device is connected to a power source, and its impedance is measured to be 10 Ω. If the resistance is 5 Ω and the inductive reactance is 8 Ω, what is the capacitive reactance?
Answer: 12 Ω
Explanation: The capacitive reactance is given by Xc = √(R^2 - Xl^2) = √(5^2 - 8^2) = 12 Ω.
