An electric current passes through a very thin filament of tungsten, which to some degree resists the current and heats up until it glows brightly. Other substances could be used, but tungsten has the advantage of having an extremely high melting point and staying strong at high temperatures.
Because it melting point is very high such as 3380 degree Celcius
An incandescent light bulb with a tungsten coil filament.
Yes
No. Tungsten is an element, where as tungsten carbide is an alloy, or a mixture of elements (tungsten, nickel, tantalum, niobium, titanium, and chromium). Tungsten carbide is much easier to work into styles and designs, but does not change the hardness of the metal.
the answer is your head your dumb rude idiotic shameless def
Yes it is small, but the power is large.
I think you probably know that the flow of electrons causes the filament to heat up and glow when the electricity is switched on and you want to know the number of electrons in the electricity? Well, it doesn't work quite like that, the electrons are all in the electron shells of the tungsten atoms making up the filament and there are the same number of electrons in these shells (and thus he filament) whether the electricity is on or off. When electricity is on, the electrons (in the outer shells) hop from one atom to the next, no extra electrons get into the filament (electrons coming in at one end are balanced by electrons going out at the other end) While all atoms have electrons, not all elements have atoms with 'free' electrons to allow this hopping - these elements will not conduct electricity.
Yes, a tungsten ring will tarnish through contact with everyday chemicals such as hand lotions and hair care products. It will develop a hard dull matte gray tarnish. You will need to use a special tungsten tarnish remover to re-shine it. Tarnish remover for silver will not work. They sell it on Amazon. Harper and Hopkins Tungsten Tarnish Remover.
it is made of tungsten and is a resistor when current flows thru it it heats up and glows
The wire inside of an electrical light bulb is called a "filament". The word filament comes from the Latin word "filum" which means "thread". In various fields there are many different types of filaments with different uses, however the ones inside of light bulbs are made out of tungsten and work by super-heating by passing electricity through it.
there is a filiament made of tungsten (wolfram; Wg) which is a special metal which shines bright at high temperature, converting the energy into light instead of heat. electricity is hot, and tungsten does not melt at high temperature. Furthermore, the vacuum inside of the bulb stops the tungsten from breaking. When a bulb is "blown", it is when the tungsten has broken which comes after lots of use, and therefore breaks the circuit of electricity. I think these bulbs are now illegal in western countries because of environmental hazards, and i have no idea how fluorescent or compact flourescent bulbs work let alone any other kind of bulb that exists now. but tungsten globes were what were light bulbs for many decades, and the ones which Thomas Edison started with.
Electricity goes through the "electrical foot contact", heats up the wires (connected to the tungsten filament) therefore lighting the light bulb up. The filament is supported by wires. The glass mount holds up the two wires connected to the filament. That is how I think the light bulb works. Have a look.

To build the light bulb.
A light bulb works by passing an electric current through the filament, which is usually made from a high resistance substance such as tungsten. When the current flows through, the filament glows which produces the light. When it burns out, no electricity passes and no glowing occurs. Source: i just know
The filament in the bulb (the thin tungsten wire inside) is heated with electricity and then it lights up. That is how incandescent bulbs work. (the old kind) CFL's (Compact Fluorescent Lights) work by a gas (possibly argon) is electrically charged and then the atoms give off light.
If there is a bulb, it should work.
There are 3 possible reasons as to why the light bulbs do not work in your refrigerator.Light bulb is blownFaulty door switchesFaulty light bulb fittings
Bad bulb, no power, no ground.
Not really, but the light bulb might not work if it's on and you put it in water.
