Tungsten, although a metal that will heat up if you pass a current through it, is not the only metal where this will happen. It happens with them all. However, tungsten has a high melting point, so it will not melt at the temperatures to which it has to be heated to give off light.

∙ 12y agoBecause it was designed to do so. Different light-bulbs use different technologies; the easiest to understand is the inefficient incandescent light-bulb: a thin wire is heated until it glows. In a fluorescent light-bulb, atoms in a gas are excited with electricity, meaning that their electrons move to higher energy levels. When they fall back, they give off light.

∙ 14y agoWell, the filament of an incandescent light bulb is what emits light. This is achieved by taking a thread of tungsten (the "filament") and suspending it in either a vacuum or an inert gas. This is done to prevent the tungsten from combustion when it heats up. The filament then has an electric charge passed through it heating the filament and causing it to emit light photons. The reason this happens is that when electrons (electricity) flow across the tungsten atom they collide with the electron of the tungsten atom causing the electrons to move to a higher energy level temporarily. The electron then emits a light photon expending energy and moving it back to its original energy level where the process starts all over again.

What is the main reason fore a light bulb to stop working?
the main reason for a light bulb to break is, the light bulb heats the tungstin wire. When the tungstin wire gets heated to much it breaks, causing thi light bulb to stop working.
