copper wire cannot be used as a filament in an electric  bulb.

Answer:
The traditional tungsten filament bulb works on the principle of heating effect of electric current.
This effect requires the filament to be of a very high resistance, so that the filament heats up and gives out light for illumination.
A copper wire has very low resistance, therefore, it is used for wires for conduction and transmission of electricity but cannot be used as a filament in a bulb working on the principle of heating effect of electric current.
