Correspondingly, why is tungsten used as a filament?
A: Tungsten is used as the filamentin incandescent light bulbs because it has the highest meltingpoint of any metal (greater than 3400 deg. Celsius) and the higherthe temperature, the greater the efficiency and whiter thelight.
One may also ask, how does tungsten filament work? When electricity flows through the filament, thelamp gives off light and gets hot in the usual way. In a normalincandescent lamp, the filament is made of tungstenmetal and surrounded by a nonreactive ("inert") gas such asargon.
Keeping this in consideration, what is the tungsten filament?
Tungsten light bulbs are named for the metaltungsten, a gray material that has an extremely high meltingpoint. Because of its high melting point and its strength, it makesfor a good filament in light bulbs. A filament is ametal wire that glows when electricity is channeled intoit.
Is Tungsten poor conductor of electricity?
Why is tungsten used in electric bulbs,although it is a poor conductor of electricity? Two reasons:it is a poor conductor, and it is tolerant of hightemperatures. The second reason for choosing tungsten isthat it doesn't melt or deform (much) at the very high temperatureof an illuminated bulb.
