Can you use a copper wire to make a filament of an electric bulb?
No, copper wire cannot be used to make the filament of an electric bulb as copper wire has very low resistance. Therefore, the bulb will not glow if current is passed. It would also melt - the filament has to be white-hot to be any use!
Why is the filament used in bulbs thin and long?
because the filament should be heated so the resistance should be high .so it uses a long and thin wire
Do you use pig hair to make a light bulb?
No, pig hair is not used to make light bulbs. Light bulbs are typically made using a combination of glass, metal, and tungsten or other types of filaments. Pig hair is not a suitable material for this purpose.
Why you use argon or nitrogen gas in light bulb?
The filament lasts for a long time because argon is inert and will not oxidize the filament even at high temperatures. If air were used, the oxygen would quickly react with and destroy the hot filament within seconds of it being turned on. Quick experiment: Attach a wire to the positive and negative sides of a large flashlight battery (the large rectangular ones with the two coils coming from the top... I can't think of the proper size). Attach the back of one alligator clip to the open end of each wire (so the clip part is not clipped on the wire). String out some steel wool until you have a single strand (or two or three wound together). This essentially is a light bulb filament. Clip it into the two alligator clips and watch how fast it burns.
What materials are used to make a microchip?
silicon wafers are used also i belive copper
Which element is used to make the filament of electric bulbs?
They're made of Tungsten.
Is mercury used for the filament in light bulbs?
No, not in the filament. You are probably thinking of compact fluorescent light bulbs, which do contain mercury.
Why is a copper wire not used to make filaments of electric bulbs?
Because the filament is in effect a resistor. Copper is too good a conductor to provide resistance to the current, and would simply allow the current to complete the circuit. The light is generated by the filament glowing as it heats up in resistance to the current. Tungsten is a much better resistor.
Why gases are used in bulbs?
In incandescent bulbs, gases (other than oxygen) prolong the life of the filament. In florescent bulbs, the gas takes the place of the filament.

Which element is used in element bulbs as filament?
tungsten
What element is used for a filament for light bulbs?
Tungsten
Why the filament of a bulb is made of tungsten but not of copper?
Because when heated, copper would react with the oxygen in the air and oxidise. Tungsten is not as reactive (I think, but check). I think Argon can also be used as a light bulb filament. Tungsten has a higher melting point than all other metals (3422 degrees C) and a very low coefficient of expansion, making it suitable for the filament in incandescent light bulbs. Argon is an inert gas used in incandescent bulbs to prevent chemical reactions which might degrade the filament.
Which element is used in which element is used in light Bulbs as a filament?
Tungsten
What is element is used in light bulbs as a filament?
Usually tungsten.
What are domestic light bulbs?
Domestic light bulbs are simply the light bulbs (usually of the filament type) used in the home.
Which element is used in a light bulb filament?
Tungsten is an element. It is used in bulbs
