Turning a conductor into an insulator

In summary, the conversation discusses the possibility of having a capacitor that is large enough to store all the free electrons in a wire, making it non-conductive. However, it is stated that no matter how positively charged a wire or plate becomes, it will not become an insulator as it will always attract electrons. The only way to change the conductive properties is to change the Z index of the material. Additionally, it is mentioned that heating up a wire will significantly increase its resistance.

This is just a hypothetical questions, but...

Would it be possible to have a capacitor so large that its able to store all the free electrons in the wire in the circuit its attached to?

Then, this would mean all the free electrons have been removed from the wire, thus making the wire non conductive...an insulator?

No matter how positive a charged wire or plate becomes it does not become an insulator. It attracts electrons, so once electrons become available they immediately start to partially fill the valence level.

The only way to change the conductive properties is to change the Z index therefore changing the material.

If you heat the wire up its resistance will go up significantly.
 

1. How can a conductor be turned into an insulator?

There are several ways to turn a conductor into an insulator. One method is by adding impurities to the conductor, which disrupts the flow of electrons and reduces its conductivity. Another method is by applying a strong magnetic field, which forces the electrons to move in a specific direction and decreases their mobility.

2. What are some examples of materials that can be turned from conductors into insulators?

Some common examples of materials that can be turned from conductors into insulators include silicon, germanium, and diamond. These materials are commonly used in semiconductor devices and have a high resistivity, making them effective insulators.

3. Can a conductor be turned into an insulator permanently?

Yes, a conductor can be turned into an insulator permanently by altering its physical or chemical properties. This transformation can be achieved through processes such as doping, annealing, or coating the surface of the conductor with an insulating material.

4. What is the main difference between a conductor and an insulator?

The main difference between a conductor and an insulator is their ability to conduct electricity. Conductors have a high number of free electrons, which are responsible for the flow of electric current, while insulators have very few free electrons and do not allow electric current to pass through them easily.

5. How does turning a conductor into an insulator affect its thermal conductivity?

Turning a conductor into an insulator can significantly reduce its thermal conductivity. This is because the same free electrons that allow for the flow of electricity in conductors also contribute to the transfer of heat. By decreasing the number of free electrons, the material's ability to conduct heat is also reduced.
