What does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb overs enough resistance to current flow, that the filament heats up so much that it will glow and produce visible light.
What is the wire inside a light bulb called?
filament
Is a light bulb a soure of light?
Yes, a light bulb is a source of light. When current is going through the filament the resistance generates enough heat that the filament glows, producing light.
Why do you need to have the glass on the outside of a light bulb?
The glass envelope, or bulb, of an incandescent light bulb is needed to hold the inert gas, such as argon, that fills the space. The filament of a light bulb is made of tungsten wire. When electricity passes through it the filament becomes extremely hot and emits light. The inert gas surrounding the filament protects it from evaporating too quickly. A light bulb only lasts as long as its filament lasts.
What element is in an incondescent light bulb filament?
Tungsten.
What type of light is a light bulb that uses a filament?
A light bulb that uses a filament is also known as an incandescent light bulb.
What is the wire that gives off light in a light bulb?
In an incandescent light bulb the wire that gives off the light is called the Filament.
What does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb overs enough resistance to current flow, that the filament heats up so much that it will glow and produce visible light.
What is the wire inside a light bulb called?
filament
How does a light bulb light?
light bulbs have metal contacts that connect to an electrical circuit and a filament. power lights up the filament in the bulb .
Light bulb filament?
What is Tungsten
What is in the center of a light bulb?
filament
What is a wire in a light bulb?
filament
What type of light contains a filament?
All kinds of incandescent lamp, and all types of light bulb contains filament. But there are several kinds of filament applied each type of light bulb.
Can you give me 2 fact about the incandescant light bulb?
-It's a very old technology quickly being replaced by newer more efficient technologies. -The light produced in the bulb is created by electricity heating up a filament inside the bulb creating light. This wouldn't be possible without the bulb however, since oxygen would quickly end this reaction of the filament through oxidation.
What is light bulb filament?
It is the extremely thin wire inside the bulb. It is so thin that when the electricity goes through produce light, when that filament breaks the bulb is not good.
Did Lewis Howard Latimer light bulb with a carbon filament?
yes he improved the light bulb that Edison invented using the carbon filament.
