What is a light bulb filament?
the filament is the metal peice in a bulb that glows.Tungsten is most often used in a lightbulb.
What is the metal in domestic light bulbs?
Tungsten in the filament of incandescent lightbulb.
What happens during a light bulb burning out?
A light bulb works by passing electricity through a long, thin piece of metal that is called a filament. The electricity heats up the filament much like an electric stove heats up its elements. The heat, through black body radiation, causes the filament to emit light. But, the heat also stretches and thus weakens the filament. Over time the weakening will break the filament along the heated portion and this is called "burning out" in common language.
What is the center of a light bulb called?
If you mean the little metal thingy that loops around, it's a filament.
Explain why the filament must be made of metal?
So it could easily pass electric current to the "metal" ,hence also producing light and non other the heat.
How did the expression 'blew out' or 'blown' come to be used to describe when a light bulb stops working since nothing actually blows up?
The filament broke.In some rare cases the filament explodes suddenly in a very bright flash of light and the bulb makes a very clear POP noise when this happens but does not break. When you replace the bulb you will notice the glass is darkened, this dark coating is recondensed metal vapor from when the filament exploded into metal vapor. So yes, sometimes the filament not only breaks or melts when it fails but sometimes the filament does indeed blow up!
What is the filament used in tubelight-?
The type of filament used in tube light is that one which is thin and surrounded by an oblong metal shield.
How does a light bulb light?
light bulbs have metal contacts that connect to an electrical circuit and a filament. power lights up the filament in the bulb .
What is metal with which the filament is made?
Assuming you're talking about light bulbs... the filament is made from Tungsten.
What is electrical energy converted into when electric current flows through the metal filament of a light bulb?
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
What is a light bulb filament?
the filament is the metal peice in a bulb that glows.Tungsten is most often used in a lightbulb.
Why does the filament in a light bulb not burn up immediately?
The 'Filament' of a lightbulb is a peice of metal with an unusually high melting
What is the metal in domestic light bulbs?
Tungsten in the filament of incandescent lightbulb.
Why scientists use tungsten metal in manufacturing the filament of the light bulbs?
it glows and emits light.
What is the difference between metal halide and mercury vapour lights?
In a metal halide light, the electricity heats a metal filament to a high temperature creating an extremely bright light. Metal ions burn off. A gas of the halide group (chlorine, bromine, iodine) reacts with the metal ions that have burned off and redeposit them on the filament. Because the filament is constantly being rebuilt, it can be brighter than a regular light bulb. Also it heats the gas to the point where the gasses give off light. So both the filament and the gasses give off light. With a mercury vapor light, mercury vapor is heated until it gives off ultraviolet light. The filament only serves to heat the mercury. It does not give off light. This light is used to excite phosphrus and other chemicals on the edge of the bulb. Those chemicals glow in the visible light spectrum. As a result, they illuminate.
When electric flows through the metal filament of a high light bulbs what is electric energy transformed too?
Heat and light. The metal filament heats up to the point of incandescence in the visible part of the spectrum.
