  1. Question 1

    Q1. During a short circuit, why does a 200W bulb filament glow brighter than a 100W bulb filament?

    • A) Lower resistance allows higher current
    • B) Higher power rating stores energy
    • C) Thicker filament emits more light
    • D) Short circuit reduces voltage drop

    Answer: Lower resistance allows higher current

    Explanation: Lower resistance increases current. Option C confuses brightness with filament thickness.
