Question

Two bulbs 60W and 100w are connected in series and this combination is connected across the mains. Which bulb will glow
more brightly? Give reason.​

Answer 1

Explanation:

When these bulb are connected in parallel, voltage across both bulb is same and power consumption will be V^2/R. In this case bulb with low resistance will consume more power and glow brighter than the bulb with high resistance, so 100W bulb will glow brighter than 60W bulb.
