An AC circuit has a resistance of 10 ohms and an inductive reactance of 10 ohms. What is its impedance?
Q1. An AC circuit has a resistance of 10 ohms and an inductive reactance of 10 ohms. What is its impedance?
Answer: 14.14 ohms
Explanation: Z = √(R^2 + X_L^2) = √(10^2 + 10^2) = √(200) = 14.14 ohms. Option B is incorrect due to wrong calculation.
