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 else can I help you with?
Why is a light bulb sealed?
A light bulb is sealed to prevent air from entering the bulb, which can cause the filament to burn out quickly. The vacuum or inert gas inside the bulb helps to preserve the longevity of the filament and ensures consistent lighting performance.
What is the filament in a light bulb made of?
The filament in a light bulb is typically made of tungsten.
In a bulb noble gas argon is used . why is argon is used instead of air in the light bulb?
Argon is used in light bulbs because it is an inert gas, which means it does not react with the filament or the glass envelope of the bulb. This helps to extend the life of the bulb by preventing the filament from degrading. Additionally, argon helps to reduce the rate of evaporation of the filament, leading to a longer-lasting bulb.
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 purpose of the filament in a light bulb with filament?
The purpose of the filament in a light bulb is to produce light when electricity passes through it, causing it to heat up and emit light.
Why does the filament in a light bulb not burn up immediately?
The 'Filament' of a lightbulb is a peice of metal with an unusually high melting
Why the electric bulb does not works if oxidation takes place inside it?
Because the filament will burn, and the filament is the part that produces the light.
Why is a light bulb sealed?
A light bulb is sealed to prevent air from entering the bulb, which can cause the filament to burn out quickly. The vacuum or inert gas inside the bulb helps to preserve the longevity of the filament and ensures consistent lighting performance.
Why is a filament light bulb not filled with oxygen?
A filament light bulb is not filled with oxygen because oxygen can cause the filament to burn quickly. The bulb is usually filled with an inert gas like argon to prevent the filament from burning out too quickly and to protect it from oxidation.
What is the filament in a light bulb made of?
The filament in a light bulb is typically made of tungsten.
Why does a light bulb turn black?
A light bulb turns black when the filament inside it gets too hot and starts to burn, creating a layer of soot on the inside of the bulb.
How bulb light?
An electrical current is passed through the high resistance filament in the bulb, causing it to become white hot and so give off light. The inside of the bulb is filled with an inert gas, such as nitrogen, so the filament does not burn up .

Why do light bulbs burn out?
Light bulbs burn out due to the filament inside them breaking or wearing out over time, which interrupts the flow of electricity and stops the bulb from producing light.
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.
