Question

We use insulated copper wire but copper is a conductor of electricity . why?

Answer 1

Answer:

The clue is in the name. Insulated.

Saying that it will conduct electricity, very well. The copper is coated in an insulator, meaning that the sides of the wire will not conduct. However, when you strip a small piece of insulation from each end, you can then connect this to a power source and current will flow.

I am assuming you mean things like transformers, which appear to be copper wire wrapped around a core. This is actually coated in argon layer of insulation.

Answer 2

We use insulated copper wire to protect us from electric shock through insulation and the electricity would flow in copper..
