Question

15. The resistance of 100 W Bulb is less mhan resistance of 40 W bulb. Explain the reason​

Answer 1

Explanation:

Power= voltage²/r

Power Is Inversely Proportional To Resistance.

Therefore higher the resistance, lower the power.

A 100 Watt Bulb has a higher power than a 40 Watt Bulb.

Hence it's resistance is lesser than the 40 Watt Bulb.
