Why electric wires get hard if its cold?
Unless otherwise specified, electric cables are insulated with a plastic material, which goes stiff in cold. If you ask for it special, you can get wires that are insulated with rubber or silicone instead, which stay soft in cold. But that costs more.
How can you tell the difference between positive and negative wires?
usually, positive wires have a blue rubber coating, whereas negative wires have a red rubber coating.
What is a material that is often used to insulate wires that conducts electricity?
Thermoplastic insulation was used a few years ago and has now been upgraded to cross linked poly vinyl. The trade name used is X-link insulation. Rubber (Thermoset) is used in some outdoor extension cords.
What is the role of insulators such as plastic rubber and cloth covering wires and other conductors in a circuit?
Insulators are used to keep electrical currents in the circuit. If they do not follow the entire circuit, it would be a "short circuit".
Why do wires have plastic around them?
The plastic won't let the electricity conduct through it

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
Which plastic is used for making wire insulation?
Electrical insulation on a wire or cable composed of plastic. Most wires and cables use plastic insulation. Some other types of insulation used on wires and cables are: enamel, cloth, natural rubber, gutta percha, ceramic, etc.
Why is plastic or rubber needed for a circuit?
plastic or rubber is on the outside of an electrical cord or circuit so that you do not get shocked. rubber and plastic help to repel the electricity, while if you were just touching plain wires, they would shock you.
Why house wires made of plastic or rubber?
House wires are made of copper. They're jacketed in plastic or rubber to keep from setting flammables on fire, to keep short circuits from happening and to keep things from being electrocuted.
What are electrical wires coated with to stop us getting a shock?
It varies- heavy cables are usually coated in a rubber compound that is sometimes enriched with graphite. Household cabling is usually coated with plastic compounds of various types.
Why wires are covered with rubber?
It is because the rubber is an insulator.people don't get electric shocks that's why wires are covered with the rubber
Do plastic or rubber around copper wires is an insulator because it allows the flow of electrons?
yes
What material could be put around the wires to insulate an electric cable and a plug?
plastic or rubber
What robots are made of?
Mostly metal, sometimes plastic and sometimes rubber+metal or rubber+plastic. Sometimes all 3.
