Want this question answered?
No, copper wire cannot be used as a filament in an electric bulb. A traditional incandescent bulb requires a filament material with a higher melting point, such as tungsten, to produce light efficiently without burning out quickly. Copper would not be able to withstand the high temperatures required for light production in a bulb.
yes you caan
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.
They're made of Tungsten.

Copper
Copper is used to make electrical wire because it is ductile and is very conductive. The ease with which copper can be worked and drawn ("pulled" or "stretched") into wire (because of its ductility) makes it a great mechanical choice for wire. And copper is highly conductive, that is, it has a low resistance to electric current flow. These two properties make copper an excellent choice to make electrical wire.
The amount of an electric motor's copper depends upon the size of the motor and the supplies used to make it. Generally, the older the motor, the more copper will be present.

High grade copper.. am I right?
Copper produces a dull thud or clunk sound when it is struck. The sound may vary slightly depending on the thickness and shape of the copper object.
