  1. Question 1

    Q1. An electrician is designing a safety circuit. She needs to calculate the impedance of the circuit when it contains both a resistor and an inductor. What is the formula for impedance in this scenario?

    • A) Z = sqrt(R^2 + Xc^2)
    • B) Z = sqrt(R^2 + Xl^2)
    • C) Z = sqrt(R^2 + Xl * Xc)
    • D) Z = sqrt(R^2 + L * C)

    Answer: Z = sqrt(R^2 + Xl^2)

    Explanation: The correct formula for impedance involves the square root of the sum of resistance squared and inductive reactance squared.
