Resistive Heating, as current passes through the filament power is dissipated from the filament in the form of heat, they are made of Tungsten which has a melting point of 3380 degree Celsius. And since the interior of the bulb contains very little to no oxygen, usually filled with argon or similar type gas. The filament cannot burn, but will degrade over time to the point where it "burns out" but in reality the filament just breaks
What else can I help you with?
What is the filament of the electric bulb made up of?
The filament of an electric bulb is typically made of tungsten. Tungsten is used because it has a very high melting point, allowing it to produce light without burning out quickly.
How a electric bulb produces light?
An electric bulb produces light by passing electricity through a filament, typically made of tungsten. The electricity heats up the filament, causing it to emit light due to incandescence. The bulb is filled with inert gases to prevent the filament from oxidizing and burning out.
What did Sir Joseph Wilson Swan's light bulb made of?
Sir Joseph Wilson Swan's early light bulb was made of a carbon filament housed in a vacuum-sealed glass bulb, which allowed for the filament to glow without burning out. This design was crucial for the development of practical electric lighting.
Why does the filament of a light bulb not burn?
The filament of a light bulb does not burn because it is made of a material, typically tungsten, that has a high melting point and is able to withstand the high temperatures generated by the electric current passing through it. Additionally, the filament is enclosed in a vacuum or inert gas to prevent it from reacting with oxygen and burning up.

What is the thin wire is an electric bulb that glows called?
The thin wire in an electric bulb that glows is called a filament. It is typically made of tungsten and glows when electricity passes through it, producing light.

What is the filament in a light bulb made of?
The filament in a light bulb is typically made of tungsten.
What was the first light bulb made up of?
The first practical light bulb was made up of a filament made of carbonized bamboo that was placed inside a vacuum-sealed glass bulb. This filament would emit light when an electric current passed through it.
What is the wire inside a light bulb called?
The wire inside a light bulb is called a filament. It is typically made of tungsten and emits light when an electric current passes through it, heating it up to produce light.
How electric bulb glow when the electric current passes through it?
When an electric current passes through a filament inside the bulb, the filament heats up due to resistance, causing it to emit light. This process is known as incandescence. The filament is usually made of tungsten, which has a high melting point and can withstand the high temperatures generated.
What does the filament of a light bulb do and what is it made from?
The filament of a light bulb is the part that produces light when an electric current passes through it. It is typically made from tungsten due to its high melting point and ability to withstand the heat generated.
Why does a bulb glow when electric passes through it?
The filament in the bulb has resistance. The current flowing through the resistance of bulb causes the filament to dissipate energy in the form of heat and light. The filament is actually glowing white-hot because of the energy it is dissipating, thus giving off light.
What is the filament in an incandescent light bulb made of?
The filament in an incandescent light bulb is typically made of tungsten.
