The (plastic) or rubber or whatever is covering a wire acts as an insulator to keep the metal parts (the conductor) of the wire from touching each other (which would cause a short circuit and possibly a fire) and from touching you when energized (which could cause a nasty shock.)

∙ 13y agoPlastic is used as it is flexible, but is an insulator (poor conductor of electricity), so the current runs down the wire and does not get transferred to anything else. It's different colours, so that the wire function can be easily identified. In simple circuits, it's either a positive, negative or earth wire, but in more complex circuits with wires carrying signals, you get lots of different colours. It's really just so you can tell which wire does what - they are generally similar underneath the plastic, but they are connected to different things in specific ways, so you need to be able to see where a wire has come from and is going to.

∙ 9y agoIt is because the rubber is an insulator.people don't get electric shocks that's why wires are covered with it

Is plastic a good condutor?
Plastic is a non conductor of electricity.
What are wires in a circuit covered in?
There are a variety of wire coverings depending on what the conductor is used for. There are also different wire coverings for different temperatures where the conductor will be used. To answer the question the wires in a circuit are covered in insulation.
Why do electrical wires covered with rubber?
AnswerBecause, it is a good insulator and won't conduct electricity. It is also flexible.It coated by rubber or plastic
Why are electrical wires not made from plastic?
electrical conducters are madfrom metal because charges can travel through metal but rubber is a insulator so the charges cant get throught it so wires are covered with rubber for safety reasons so you don't get a shock.
Why electric wires are covered with insulator?
If electric wires weren't covered with insulation, there would be short circuits.

Why are household electric wires covered with plastic or rubber?
Household electric wires are covered with plastic or other materials as insulation to prevent short circuits and fires, and to prevent electric shocks.
What is the twisted wire pair?
Ethernet cable. 8 wires in 4 pairs. The wires are twisted around each other and covered with a plastic tube to help prevent interference. The wires are also each in plastic.
Why do electrical wires covered with rubber?
AnswerBecause, it is a good insulator and won't conduct electricity. It is also flexible.It coated by rubber or plastic
Why are copper wires covered in plastic?
Copper is a good condutor of electricity while plastics is a poor conductor of electricity.
Why do you use conducting wires to cover electrical cords attached to household appliances?
I believe you've managed to turn wires inside out. (conducting) wires are covered in insulating plastic. And it is done this way to prevent electrical energy from going where it is not wanted, such as into you.
Why are electrical wires not made from plastic?
electrical conducters are madfrom metal because charges can travel through metal but rubber is a insulator so the charges cant get throught it so wires are covered with rubber for safety reasons so you don't get a shock.
What are the hoops in hoop skirts made out of?
The hoop wires themselves are made of two wires covered with either plastic or buckram. They're inserted into casings on the underside of the skirt, and most skirts have four to six wires spaced about 10 inches apart.
Why electric wires are covered with insulator?
If electric wires weren't covered with insulation, there would be short circuits.
What does the plastic over the metal wires in circuit do?
In electrical wires the plastic insulates the wires to prevent a short circuit or electrocution. Different coloured plastic can aid identification of individual wires. The plastic coating can also prevent rust and prolong durability.
