An electrical filament is a thread of metal, usually tungsten, which is used to convert electricity into light in incandescent light bulbs (as developed in 1874 by Alexander Lodygin and in 1878 by Joseph Wilson Swan, among others), and into heat in vacuum tube devices.

∙ 13y agoA bulb that is lit up by using a piece of very thin wire coiled round that has electricity flowing through it very fast which causes it to heat up and is so hot that it glows white. This is why filament bulbs are not very efficient as they produce so much heat which is just not needed and is wasted.

What is the function of a filament?
On a standard incandescent light bulb, the glass traps a set of gases around the filament that help keep the filament from burning up quickly. (The filament is the part that does the actual glowing inside the glass.) It also keeps the oxygen in the air that we breathe away from the filament. Oxygen is one of the gases that will vastly accelerate the destruction of the filament. (Also, the glass keeps anything from touching the electrical conductors inside.) The glass can also act as a filter to remove any ultraviolet radiation caused by certain types of light bulb's ("lamp's" technically) methods of creating a arc to produce light. When specially teated, the glass can also be used to break up the light rays to cause more diffused source of light. (Think "Soft White" to get an idea.)
What is the part of a flower which holds up the anther?
Filament
What is the job of the filament?
Filament provides support to the anther
What are hair like filaments of fungi?
In an incandescent light bulb (the kind that screws into a standard light socket), the filament is the piece of metal in about the middle of the glass bulb that glows and emits light and heat when electricity passes through it. It is usually made of tungsten, but originally was made of carbon. New compact fluorescent and LED-based light bulbs do not really have filaments like incandescent light bulbs. Filament is a term also used in astronomy and biology for different things, but these uses are not as common as in light bulbs.
What is the flower part that elevates the anther?
The filament is the part of the flower that elevates the anther.

What is filament in a bulb?
The filament is the small coil that glows when the bulb is on. I believe its made out of tungsten
What is filament shaped into?

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.
Which has the thickest filament - a high-resistance or a low-resistance bulb?
A low resistance bulb has a thicker filament.
What is the wire inside a light bulb called?
filament
What the filament of bulb is broken then it is called?
Fused bulb
What is a light bulb filament?
the filament is the metal peice in a bulb that glows.Tungsten is most often used in a lightbulb.
What is the general resistance of a tungsten filament?
The resistance of the filament in a light bulb is(voltage at which the bulb is designed to operate)2/(the rated power/watts of the bulb)
What is a fuse bulb?
a fuse bulb is a bulb in which the filament of the bulb burns and it stops working
