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!

How does a dry cell make a lightbulb light?
When electric current flows through filament of the bulb, the electrons are squased among themselves due to the thin structure of the bulb. This causes them to emit light. Due to the gases filled in the light bulb, the bulb glows.
How does an electric current produce light?
By heating a metal wire called a filament. In a light bulb (lamp) the electric current flows through a tungsten filament which glows white hot giving off light.
What is the name of the particle which flow through copper in order to make a light bulb light?
It is called metal,plastic or steel so copper is also magnetic which alows the copper to make the bulb be brighter and to light up thankk you for listening...
How does a light bulb make light?
It does first of all depend on what kind of light bulb we are thinking about. The traditional light bulb consist of a glass bulb with a filament made out of Tungsten/Wolfram (Two names, same thing.) This filament is highly heat resistant as long as it is placed in vacuum or have an inert gas around it. When you turn on the power to the light bulb, then electrons starts to flow through this filament. This flow of electrons is massive as a lamp bulb is basically a pure shortcut of electrical power. Due to the massive flow of electrons, they collide and interact with each other. This causes the filament to heat up. As the filament heats up, the activity of the electrons increases. Each electron demands more space and this effect limits the possible current with a given voltage. The filament gives off to us visible light because of the changes in energy levels of atoms and electrons in it. often when two electrons collide, one looses a little bit of its power and this is given of as a photon. Billions upon billions of this happening in the filament and voila. We have a source of light. Electrons pass through the filament of a light bulb and cause the energy/heat to build up. Photon's are given off when an electron drops down in it's energy level, with a light bulb the photons are seen as visible light.
Why did Thomas Edison fail 1000 times?
Edison failed many times - no one knows how many - to make a filament for a light bulb that would last a long time. He did not invent the light bulb - he was working on a BETTER light bulb that would last longer.
Can you use copper wire to make the filament of bulb?
yes you caan

Is resistance in the filament of a lamp essential or not?
Yes, the resistance of the filament of a light bulb is what generates enough heat to make the filament glow and produce light.
What year did Louis Lattimer make the filament for the light bulb?
2008
What type of filament will make the light bulb turn on for a longer period of time?
The filament is nothing to do with the light turning on, that is controlled by the switch.
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.
How does the inactivity of noble gases make them useful?
We use them as atmospheres when we don't want something to react, particularly with oxygen. For instance in a filament electric lamp, the tungsten filament gets extremely hot. If the bulb contained air, the filament would oxidise immediately, as it does if the glass develops a crack. That's why we fill them with argon.
What forms of energy does the electric light bulb made?
First let us understand the different parts that go to make up the light bulb shall we? The key component in a light bulb is the filament, this filament, ususually a thin piece of wire, is connected to two contact points. These points are then connected to the metal base of the bulb. When the bulb is attached to the light socket a circuit is then made. As the thin wire is part of the circuit it will have electicity passing through it when the power is switched on. The bulb glows because of the filament is thinner than that of the rest of the circuit. The filament gives off heat energy and begins to glow, this glowing we call light energy. You now have two forms of energy.
Which element is used to make the filament of electric bulbs?
They're made of Tungsten.
How does an electric current produce light?
By heating a metal wire called a filament. In a light bulb (lamp) the electric current flows through a tungsten filament which glows white hot giving off light.
Is electric bulb glowing a example of chemical or physical changes?
It is a physical change. When you supply electricity, the electrons jump to higher energy state. When they come back to their level, it emits energy which falls in the visible region of light. The atoms of the filament (Tungsten) are not going through any change, that changes their chemical properties. Tungsten, still remains tungsten!
You are using a bulb whose filament is broken will the bulb glow when connected to battery give reason?
no. it cant make its connection so it wont make any light.
