So that if a spark of light fall or flickers, it won't catch on fire.

The light bulb's glass shell is a containment vessel It surrounds the filament and contains an inert gas. By not exposing the hot filament to surrounding oxygen, the life of the filament is extended.
Uranium is not commonly used in light bulbs. Light bulbs typically use tungsten filaments to produce light when an electric current passes through them. Uranium is more commonly used in nuclear reactors to generate electricity.
Tungsten is a greyish white element commonly used in lamp filaments. It has a high melting point and can withstand the high temperatures generated when electricity passes through it, making it ideal for use in light bulbs.
No, bulbs do not make use of magnets to work. Light bulbs function by passing electricity through a filament, which then emits light and heat. Magnets are not involved in the process of generating light in bulbs.
Tungsten is the most commonly used element in filaments due to its high melting point and ability to emit light when heated. Alternatively, some filaments also use carbon or other metals like osmium or rhenium.
Fluorescent light bulbs use phosphors to convert ultraviolet light into visible light.
Tungsten is used in filaments of light bulbs.
Modern light bulb filaments are usually Tungsten not Carbon. However early bulbs used things like silk coated with Carbon. Filament means thin thread. The bulbs are filled with inert gas like Argon to stop the filament from burning up with oxygen. Arc lamps use Carbon rods though.
no they are two different things....LED use semiconductors for light production...whereas bulbs use filaments....nothing uses any other...

Edison used carbonized bamboo and then switched to carbonized cotton threads as materials for his early filaments in his incandescent light bulbs.
Incandescent light bulbs use tungsten( a metal which can withstand very high temperatures) as filament.When heated to a very high temperature, the filament glows emitting light and heat. Heating effect in filaments is caused by the property of resistance in conductors. On reducing the cross- section area( thickness) of the filament, its resistance is increased and hence the filament glows with comparitively lesser electric current.
It used to be. Lots of toys have small light bulbs in them, and the filaments in light bulbs are made from tungsten. In modern times, they're more likely to design those toys to use LEDs, which are tungsten-free.
Light bulb filaments are usually made of tungsten, which has a very high melting point. Occasionally carbon is used as a filament.
Thomas Edison used carbonized bamboo as a filament in his early light bulbs. He later experimented with other materials such as carbonized cotton thread and finally settled on a carbonized bamboo filament for commercial light bulbs.
Light bulb filaments.
The metal used in domestic light bulbs is typically tungsten. Tungsten has a high melting point and is able to withstand the high temperatures generated by the electric current passing through it, making it ideal for use in light bulb filaments.
