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.

∙ 7y agoWhat 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.

What is it called when a wire is coated in plastic to surround the wire are called?
Insulation
The term magnetic wire indicates a wire that has what for insulation?
Magnetic wire has a coating of varnish for an insulation.
What acid can you use to remove the rubber coating opf an electrical wire?
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.
What metal is used in household electric wiring?
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.
Why is a plastic coating around a wire?
For insulation.
Is a plastic coating on wire a conductor or an insulator?
insulator
Why does the charge flow through the copper wire but not the plastic coating that covers it?
Because plastic is Not Metal and the penny is.
Preparing the wire by coating it with solder is called?
Tinning
When you preparing a wire by coating it with solder what is it called?
It is known as tinning.
What is it called when a wire is coated in plastic to surround the wire are called?
Insulation
What is the function of the red wire?
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.
Is wire coating an example of thermosetting plastics?
yes wire coating is an example of thermosetting plastics!!!!
What are the ingredients of c4?
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.
What finishes can be applied to metal?
- coating with another metal - paint coating - plastic coating
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.
