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.
What would be the point of coating copper wire with copper? Why not just make thicker wire?
Electrical copper wire is coated with plastic because plastic is an insulator so that you can touch the wire without electrocuting yourself.
The plastic coating around a wire protects the wire, and helps to separate them. Bare wires can be very dangerous, so it's required for safety as well as performance.
Insulation. Several insulated wires with an outer jacket make up a cable.

Insulation
Magnetic wire has a coating of varnish for an insulation.
If you insist on removing the rubber coating on a wire chemically, try using acetone. Otherwise, throw it in a fire or use old fashioned wire strippers.
Yes, because to conduct electricity you need a metal wire, (usually copper). However they have a plastic outer coating (sheath) which protects them and insulates them.
For insulation.
insulator
Because plastic is Not Metal and the penny is.
Tinning
It is known as tinning.
Insulation
Red normally is a live wire. However, it's just a matter of a plastic coating over the wire, and a red wire can be connected any way someone wishes to on any circuit.
yes wire coating is an example of thermosetting plastics!!!!
C4 is made of an explosive called RDX with a coating of plastic over it. Think of it as an explosive in a block of plastic as a container.
- coating with another metal - paint coating - plastic coating
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.
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.
