Two Incandescent light bulbs of 40 W and 60 W rating are

Home » Network Theory » Network Elements and the Concept of Circuit » Question

Two Incandescent light bulbs of 40 W and 60 W rating are connected in series across the supply voltage, V then—

1. the bulbs together consume 100 W
2. the bulbs together consume 50 W
3. the 60 W bulb glows brighter.
4. the 40 W bulb glows brighter.

Correct Option: C

As the bulbs are connected in series, and power,
P = I² R
Current in the series connection will remain the same
i.e. P ∝ R
It means higher rating bulb will glow bright.
