  1. Question 1

    Q1. A cell with a high internal resistance has a low electromotive force (EMF). Which process is responsible for this relationship?

    • A) Osmosis
    • B) Electromagnetic induction
    • C) Chemical reactions at the electrodes
    • D) Internal resistance increasing with temperature

    Answer: Chemical reactions at the electrodes

    Explanation: Internal resistance and EMF are inversely related due to the increased chemical reactions at the electrodes, making option C a plausible but incorrect answer.
