Filament

A very thin tungsten wire inside an incandescent light. When heated, it glows and emits light.

filament

[′fil·ə·mənt]
(astronomy)
A prominence, seen as a dark marking on the solar disk.
(botany)
The stalk of a stamen which supports the anther.
A chain of cells joined end to end, as in certain algae.
(electricity)
Metallic wire or ribbon which is heated in an incandescent lamp to produce light, by passing an electric current through the filament.
(electronics)
A cathode made of resistance wire or ribbon, through which an electric current is sent to produce the high temperature required for emission of electrons in a thermionic tube. Also known as directly heated cathode; filamentary cathode; filament-type cathode.
(invertebrate zoology)
A single silk fiber in the cocoon of a silkworm.
(metallurgy)
A long, flexible metal wire drawn very fine.
(science and technology)
A long, flexible object with a small cross section.
(textiles)
A single continuous manufactured fiber which is extruded from a spinneret and joined with others to make a thread.
