Well, isn't that a happy little question! Copper can indeed be used to make filaments for light bulbs. Its high melting point and excellent conductivity make it perfect for this purpose. Just imagine all the beautiful light that filament will create, lighting up the world with its warm glow.
What else can I help you with?
Why not iron filament used in bulbs?
Iron filaments are not used in light bulbs because they have a relatively high melting point and poor conductivity compared to tungsten, the metal commonly used in filament bulbs. Iron would not produce as much light or last as long as tungsten in a filament bulb.
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 do you use argon in filament light bulbs?
Argon is used in filament light bulbs to displace oxygen and prevent the filament from burning. It creates an inert atmosphere inside the bulb, helping to prolong the life of the filament and improve the overall efficiency of the bulb.
What is a filament that glows white hot in electric light bulbs?
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
Is argon used in light bulbs?
Yes, argon is commonly used in incandescent light bulbs. It is often used to fill the space around the filament inside the bulb, helping to prevent oxidation and prolong the life of the filament.
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
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.
Why not iron filament used in bulbs?
Iron filaments are not used in light bulbs because they have a relatively high melting point and poor conductivity compared to tungsten, the metal commonly used in filament bulbs. Iron would not produce as much light or last as long as tungsten in a filament bulb.
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.
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!
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
