Question

Explain why a filament bulb gets hotter than a low energy bulb of the same brightness.

Answer 1

Answer:

Because the filament is so thin, it offers a good bit of resistance to the electricity, and this resistance turns electrical energy into heat. The heat is enough to make the filament glow white-hot. Unfortunately, this isn't very efficient. Most of the energy that goes into an incandescent bulb is lost as heat.

Answer 2

Explanation:

It's all a matter of relative resistance. The amount of current flowing through the wire and the bulb is the same. The power dissipation in a circuit element is proportional to I2R where I is the current and R is the resistance of the element
