The filament inside is heated. Once it gets hot enough, it dissipates some of the energy as heat and light.

What is the difference between a filament of a bulb and an element of an electric heater?
The heater element is thicker wire, and has lower resistance. It still has enough resistance to glow red hot (producing heat) but does not glow white-hot and very brightly like a light bulb filament. Also, it lasts almost indeifnitely. whereas the light bulb filament has a finite life - it will "burn out" sooner or later.
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 causes filament in a light bulb to glow?
Current passing through a special wire like tungsten heat up the wire and create light by emitting photons
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.
What temperature does a filament inside a light bulb reach?
Answer:The filament inside the light bulb reaches over 3000 degree Celsius.
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.
Is resistance in the filament of a lamp essential or not?
Yes, the resistance of the filament of a light bulb is what generates enough heat to make the filament glow and produce light.
How does a battery make a light bulb glow?
The flow of electrons from the battery flow through the filament in the bulb causing it to get hot and glow thus producing light.
Why does a fused bulb not glow?
A fused bulb does not glow because the filament of a fused bulb is broken. Since current can't flow through the filament, it can't get hot enough to glow.
Why is gas in a light bulb?
Mainly to prevent the filament, the glow wire from burning up.
Does the filament of an incandescent light bulb glow because it gets extremely hot?
yes
Is a light bulb a gas?
Mainly to prevent the filament, the glow wire from burning up.
Will the bulb light if the filament is broken Why?
No, the broken filament breaks the connection which electricity needs to complete the circuit.

What does a light bulb have to do with an electrical light source?
A light bulb is a source of electric light. In an incandescent light bulb, the glass bulb forms a protective shield around a glowing filament. The air inside the glass bulb is removed, or replaced with an inert gas. Electric current is passed through a thin metal filament (usually tungsten), which causes it to glow white hot, giving out light. The protective bulb stops the filament from burning up, as it has no Oxygen.
What happens when a battery light the light bulb?
When the switch is turned it completes an electrical circuit. The circuit amperage flows through a high resistance filament in the bulb and it starts to glow. The bright glow from the filament and the reflector behind the bulb is what creates the flashlights beam.
The part of a light bulb that is a poor conductor so that the friction causes it to light up and glow?
That part of a light bulb that causes light to light up is called the filament, and it is typically made from tungsten.
