  1. Question 1

    Q1. The impedance of a series LCR circuit is given by

    • A) √(R² + (Xl - Xc)²)
    • B) √(R² + (Xl + Xc)²)
    • C) R + Xl + Xc
    • D) R + Xl - Xc

    Answer: √(R² + (Xl - Xc)²)

    Explanation: Z = √(R² + (Xl - Xc)²), where Xl is inductive reactance and Xc is capacitive reactance.
