Filament example sentences

Most of the power consumed by the filament appears as heat, but a small part of it is in the form of light radiated.However, if the current through a circuit is too weak, the filament does not get heated sufficiently and it does not glow.A strong metal with high melting point such as tungsten (melting point 3380°C) is used for making bulb filaments.Could you identify the anther and the filament of a stamen? [Figureure 1 9 (a)].Each stamen consists of a slender filament with an anther at the tip.Here, the filament must retain as much of the heat generated as is possible, so that it gets very hot and emits light.It is a creeping, green, branched and frequently filamentous stage.The bulbs are usually filled with chemically inactive nitrogen and argon gases to prolong the life of filament.The plant body may be unicellular, colonial or filamentous.They range from simple branched, filamentous forms (Ectocarpus) to profusely branched forms as represented by kelps, which may reach a height of 100 metres.The size ranges from the microscopic unicellular forms like Chlamydomonas, to colonial forms like olvox and to the filamentous forms like Ulothrix and Spirogyra.The filament should be thermally isolated as much as possible, using insulating support, etc.Tungsten is used almost exclusively for filaments of electric bulbs, whereas copper and aluminium are generally used for electrical transmission lines.It is used as an abrasive for sharpening hard tools, in making dies and in the manufacture of tungsten filaments for electric light bulbs.It may have happened in Activity 1 What can be the reason? Do you remember why the bulb glows when the electric current passes through it? Due to the heating effect of current, the filament of the bulb gets heated to a high temperature and it starts glowing.
