  1. Question 1

    Q1. When a battery powers a circuit, which quantity depends on the load’s resistance?

    • A) Battery’s EMF
    • B) Battery’s internal resistance
    • C) Terminal voltage
    • D) Battery’s material resistivity

    Answer: Terminal voltage

    Explanation: Terminal voltage = EMF - Ir. Internal resistance and EMF are intrinsic. Resistivity is material property.
