Why do lightbulbs get so hot?

Answer 1

The main component of an incandescent light bulb is the metal filament (the spiral). The filament is heated up by the AC current, when the lamp is turned on. The heat excites the metal ions so much that they radiate energy in the form of light. The spectrum of the radiation spans from visible (the warm light you can see) to invisible (infrared, which is heat). Heat is really infrared emission, which is still 'light' in physics terms.

Answer 2

Because of IxIxR loss. which in turn gives a heating affect. What the statement above means is that inside an incandescent bulb, the electric current heats the filament to a temperature high enough to cause it to glow brightly. This heat gets transferred to the glass envelope.

Answer 3

An average 60-watt bulb has over 6-feet of filament wire inside of it. When the bulb is turned on, electricity passes through the filament, heating it up to produce light. Most of the electricity flowing through the filament generates heat, while a small part generates light.

Answer 4

The current is delivering energy to the filament in which it lights up and gives of heat.

Answer 5

moving electrons in the current of the bulb are moving so fast that they produce friction,making the bulb hot

Answer 6

The heat is actually the main point of the light bulb.

The wire inside the bulb is heated with electricity until it's so hot that it starts to emit light.

Answer 7

Electricity passing through the filament not only produces light, due to the filament's resistance, but also heat.

Answer 8

Because as electricity is passed through the filament, light is given off, heat is just a side effect of the light being on. Energy efficient lights give off more light and less heat.

Answer 9

yes it does
