A filament is a fine, thinly spun thread, fiber, or wire. Originally the term referred primarily to animal or vegetable structures, but with advances in technology it is frequently used to refer to human-made objects including filaments of incandescent light bulbs. Incandescence is the release of electromagnetic radiation from a hot body due to its high temperature. ... The incandescent light bulb uses a glowing wire filament heated to white-hot by electrical resistance, to generate light (a process known as thermal radiation). ...

In biology, a filament is a long chain of proteins, such as found in hair, muscle, or in flagella. A flagellum (plural, flagella) is a whip-like organelle that many unicellular organisms, and some multicellular ones, use to move about. ...

Contrary to fibres (or staple fibres) which are cut to a selected length, the word "filament" is used in the textile industry to designate an endless or continuous object, the length of which is only limited by the capacity of the spool whereon the filament is wound. For the meaning of fiber in nutrition, see dietary fiber. ...

An electrical filament is used to convert electricity into heat and/or light and refers to elements made of some kind of wire. Filaments are commonly found in traditional light bulbs and vacuum tubes. Electricity is a property of certain subatomic particles (e. ...
