What happens when there is no plastic coating on a electrical wire?

Nothing happens. The wire will still conduct electricity. An example of this is the overhead utility wiring. The insulation on a conductor is there strictly to keep the conductor from touching any thing that would ground the conductor. This grounding could be from another adjacent conductor or a grounded medium around the conductor. A grounded conductor will trip the over current protection and trip the circuit off line. Without an insulation on the wire multiple wires in a conduit could not be utilized.

Which of the following materials would be the best insulator for an electrical wire?
P.V.C or polyvinylchloride. It's a plastic.
What is a poor conductor of electricity and is used to coat wires?
In low voltage wires, the insulation factor of the coating determines the wire's voltage rating. A wire coating of cross linked poly vinyl is used as an insulation. High voltage transmission wires uses no coating on the wire
Preparing the wire by coating it with solder is called?
Tinning
What type of cable consists of a single copper wire surrounded by at least three layers an insulating material and woven or braided metal and a plastic outer coating?
The description if that of "coaxial cable".
What happens if you touch an exposed electrical wire?
If the wire is carrying an electrical current, and if the current has enough voltage, the current can leave the wire and pass through your body. This is painful, and can causes burns or death.
Why is a plastic coating around a wire?
For insulation.
What is the plastic coating on the wire called?
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.
Is a plastic coating on wire a conductor or an insulator?
insulator
Why is there usually a plastic coating around a metal wire?
There are a number of reasons: If the wire is electrical then it is covered in plastic as plastic provides insulation, this means that if adjoining wires come into contact the electrical current would not cause a short circuit. Normally electrical wire is cooper as it is a good conductor of electricity and does not oxidize/ rust easily. Secondly wire hangers are covered in plastic to prevent the metal (normally mild steel) from rusting. If they were to rust, it would cause orange/ red stains on your clothes.

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.
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.
Why is electrical wir coated with plastic?
The electric wire is coated with plastic to serve as an electric insulator.
Which wire would make the bulb dimmer copper or plastic or gold?
plastic as its the worst electrical conductor
Is there a coating you can put on electrical wiring to reduce the temperature?
Not that I have ever heard of. Electricity produces heat and heat is the cause of most electrical problems. The wire is heating because too much current is being conducted for the size of the wire. You need to either replace the wire with something larger or add another wire. The temperature of the wire has nothing to do with the coating, the heat is being generated inside the wire when excessive current is passing through.
What are wire cables?
they are a pieces of metal covered in plastic coating (for insulation) that deliver electricity to an electrical object e.g. TV act as a connection to the earth system of the appliance/house. They are also cables which are armoured for TV aerials etc
What are 15 things made out of wire?
Fifteen things made out of wire include:chicken wire (fencing)wire basket (kitchen item)braces (for teeth)electrical and telephone wires (with insulating coating)coat or clothes wire hangersstereo speaker wire (with plastic coating)(landline) telephone cord (indoor, from jack to phone; covered with plastic coating)a spring in an expandable hair clipcar battery cable wires (coated)other car engine wiring (coated)the insides of a lampelectrical wiring in a house or building (coated; insulated)wire connectors between a furnace fan / motor and the furnacecomputers (coated; soldered to components in a laptop or desk top), or other electronics (boom box; stereo; radio)any small motor, for example, in an electrical desk fan, box fan, etc.grates used as platforms in cages for small animalsto attach and hold boards together (example, some smaller fencing)
