Filament is a thin, flexible wire-like structure that is often found in light bulbs. It is the part of the bulb that glows when electricity passes through it, producing light. Filaments can also be found in other electronics, like heaters or electric cooktops, where they are used to generate heat. The word filament can also be used more broadly to refer to any long, thin, and flexible material, like a piece of string or a hair strand.
