Plastic or rubber is used as insulation around electrical wires, keeping them from contacting other parts of a circuit, and from grounding out to conductive materials. Where insulation is removed or damaged, a spark or short could cause fires or other damage.

Why does the charge flow through the copper wire but not the plastic coating that covers it?

The copper wire is a conductor that allows electric charges to flow through it easily due to its free-moving electrons. The plastic coating, on the other hand, is an insulator that does not allow electric charges to flow through it because its electrons are tightly bound to their atoms, preventing the flow of electricity.

What object uses both an insulator an conductor?

Elecrical wire is an great example of this. the copper wiring is the conductor of electrons and the plastic coating insulates the wire absorbing some heat from friction and it's impermeable to electrons not allowing them through outside the wire.


What is a different between the insoluted wire and other wire?

It is not 'insoluted wire'. That one in named as ' insulated wire' Usually metallic wire carries the current. Just to avoid electric shock it is to be covered by insulators such as rubber or plastic. Some times we use nickel coating which also serves the purpose of insulation.


What are telephone made of?

Mainly all telephone wires are made of copper with a plastic coating for insulation. Older form of telephone wire had a paper or pulp insulation over the copper wire. They are also a twisted pair cable.
