Because it has a very very high melting temperature: 6191F, 3422C. However it is also
very difficult to work with, so early light bulbs used carbon for making the filament instead.
Around the year 1900, carbon filaments were replaced with tantalum filaments. It was not
until about 1910 that it became practical to make tungsten filaments.
This incandescent filament emit light.
Filament of bulb is made up of Tungsten.perfect answer:filament of bulb made of tungsten because of its melting point tungsten s m.p. is 3422 c and it produces through a method called extrusion process and due to its high melting point it do not melt due to heat. thnx if any1 have some general knowledge plz send me at wanted_rk2000@yahoo.comTungsten.
As an incandescent light bulb is used, tungsten slowly evaporates from the filament causing it to get thinner. When it gets too thin it can no longer carry the current and part of it melts causing the bulb to blow out.
A light bulb glows because of a very fine wire inside the glass bulb called a 'filament'. When an electrical current is put through the filament, assuming the voltage is high enough, it will begin to heat up and glow because such a small wire cannot handle the flow of electrons and has to discharge them through heat and light. Also if you put to much voltage in it will heat up the filament too much and melt it. Incandescent (filament) light bulbs fail over time because they slowly lose small amounts of wire until the filament breaks and stops glowing.
Fluorescent tubes create ultraviolet light when electricity is passed through mercury vapor. The UV light causes the phosphors, dusted over the inside of the tube, to fluoresce--or give off visible light. Three of the elements found in the tube would be: Phosphorous, mercury, and tungsten.
tungsten <<>> Also along with the above, aluminium for the shell, steel for the filament holders, and in past years brass was used for the shell until manufactures found out it was cheaper to use aluminium for the job.
What is Tungsten
Tungsten.
Tungsten
Tungsten.
Inside a tungsten-halogen bulb, electrons flow through a tungsten filament. The filament heats up and emits light.
Usually an element called tungsten.

Usually tungsten.
the filament is the metal peice in a bulb that glows.Tungsten is most often used in a lightbulb.
The physical property that can render tungsten suitable for making filament of tungsten light bulbs is incandescence.
Usually tungsten.
