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.

What elements make electric cable?
Copper and aluminium are used for electric cables.
What percentage of copper in Electric generator?
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.
Copper is used to make electric wire because it is a good what?
ductile. You must have the same worksheet as I do.
The individual filaments that make up the body of fungus are called?
Individual filaments that make up the body of a fungus are called hyphae.
Thin filaments at either end of the sarcomere are attached to interconnecting filaments that make up the what?
Z lines
What elements make a light bulb possible?
For an element to be eligible for a light bulb, it should be highly malleable and should have a very high melting point. Tungsten is one such element which is extensively used to make filaments of electric bulbs.
Why is a copper wire not used to make filaments of electricbulbs?
Copper wire has low resistance, so it is unable to produce enough heat to glow.
Is titanium used to make the filaments in light bulbs?
Tungsten is used because it has a high melting point and maintains a high strength at high temperatures - like those required to make it hot enough to give off light as a filament in an electric bulb.
What elements make electric cable?
Copper and aluminium are used for electric cables.
Which element is used to make the filament of electric bulbs?
They're made of Tungsten.
What metal is usually used to make a electric wire?
Copper
How many uses does tungsten have?
Hundreds. It is used as filaments for light bulbs, combined with carbide to make really tough cutting tools, and as shielding for nuclear radiation.
Why is copper commonly use to make electric wires?
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.
What percentage of copper in Electric generator?
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.
Can you make electrical energy using two candles?
because they have an crude examples of what we call an electric filaments lamps. Thats why they they producan energy.
What metal are use to make electric wire and why?
copper plated aluminum wire
