MDCAT Physics MCQ #1

  1. Question 1

    Q1. The rms value of an AC is defined as the value of that DC which produces the same heating effect in a given resistance.

    • A) Average power dissipation
    • B) Peak current
    • C) Root mean square current
    • D) Instantaneous current

    Answer: Root mean square current

    Explanation: RMS current is defined as the DC that produces the same heating effect; 'Average power dissipation' is a related concept, not the definition.
