  1. Question 1

    Q1. A series RLC circuit is in resonance. What is the phase difference between voltage and current?

    • A) 0 degrees
    • B) 90 degrees
    • C) 180 degrees
    • D) 45 degrees

    Answer: 0 degrees

    Explanation: At resonance, the circuit behaves resistively, so voltage and current are in phase. Option B is incorrect as it's the phase difference for a purely inductive or capacitive circuit.
