  1. Question 1

    Q1. The power factor of a series LCR circuit is 1. What is the state of the circuit?

    • A) Resonance
    • B) Capacitive
    • C) Inductive
    • D) Purely Resistive

    Answer: Resonance

    Explanation: Power factor = 1 implies the circuit is in resonance, as XL = XC, making the circuit behave like a purely resistive circuit.
