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.

Insulation
Magnetic wire has a coating of varnish for an insulation.
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.
thermo plastics
insulator
A plastic coating around a wire is used to provide insulation and protection. It helps to prevent electrical shocks, short circuits, and corrosion. It also helps to keep the wire stable and maintain its shape.
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.
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.
yes wire coating is an example of thermosetting plastics!!!!
- 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.
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.
