Tungsten Used Almost Exclusively For Filament Of Electric Lamp at JENENGE blog

Tungsten Used Almost Exclusively For Filament Of Electric Lamp. In 1903, w d coolidge reduced tungsten oxide to the metal and then. Also, its vapour pressure is very. The main reasons why tungsten is used in light bulbs is because it has a high melting point, high electrical resistivity and is far more durable. When an electric current passes through the tungsten filament in an electric bulb, the resistance of the filament to the flow of the electric current causes it to heat up. The first incandescent lamps consisted of a filament of carbon wire in an evacuated glass bulb, two ends of the wire being brought out. Pure tungsten is one such element used for making bulb filament as it has the highest melting point of 3695k. Why is tungsten used in the filaments of electric bulbs? Pure metallic tungsten was used for the filaments of old style incandescent light bulbs. Incandescent bulbs work by heating a metal. The filament becomes so hot that it begins to emit light, creating the bright glow we see in incandescent light bulbs. Tungsten has the highest melting point (3695 k), lowest vapour pressure and greatest tensile strength among all the metals. Tungsten is a valuable metal that is commonly utilized in light bulb filaments, electron and television tubes, abrasives, and specific alloys.
