MDCAT Physics MCQ #56

  1. Question 1

    Q1. The power factor of a purely resistive circuit is

    • A) 0
    • B) 1
    • C) 0.5
    • D) -1

    Answer: 1

    Explanation: In a purely resistive circuit, voltage and current are in phase, so power factor = cos(0) = 1. Option A is incorrect as it represents a purely inductive or capacitive circuit.
