Turning a conductor into an insulator

[IssacBinary]

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?

 

[LostConjugate]

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.
