How can a copper wire be made a non-conductor of electricity?

Answer 1

This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask the answer of. Earn your diploma.

Answer 2

A SIMPLE ANSWERA conductor of electricity can be made out of any piece of metal wire such as some copper lamp cord or flex or battery cable jumpers or even a metal coat hanger.

A conductor of electricity cannot be made out of dryplastic, wood, paper or any other material which is an insulator.

A MORE COMPLICATED ANSWERIs this question is asking how anyone could make an electrical conductor from scratch? If so, that is something which would be really difficult to do because you would have to do the same things as big industrial companies must do to make wires.

If that is the question, then the answer to it is: you have to dig into the earth to find the right kinds of stone which have the right kinds of metal ores in them. (Ore = stone containing metal compounds.)

Then you have to smelt and refine the ores to get the pure Iron, Copper, Silver, Gold, or Aluminium metals which are good conductors of electricity.

Then you have to roll and draw the refined metal into different size electrical wires and, finally, coat the wires with plastic insulation.

To be able to do all that you would have to dig a mine in the ground and build a huge factory - also you would have to employ a lot of skilled people - and to do all that costs many millions of dollars.

Answer 3

To make a copper wire a non-conductor of electricity, you can coat it with an insulating material such as plastic or rubber. This insulating layer prevents the flow of electrical current through the copper wire by blocking the movement of electrons. Additionally, you can remove the free electrons from the copper wire by subjecting it to high temperatures, which will disrupt its ability to conduct electricity.
