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.
Why does the electric wire become loose in summers?
The metal wires expand in the heat - making them sag.
What objects can be stretched?
socks, dough, clay, bed sheet and rubber band
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 magnet formed by electricity called?
Electromagnet. This is a type of magnet which the magnetic field is produced by the flow of electric current through wires generally surrounding a metal or iron core. Electric motors, generators, relays, loudspeakers, hard disks are examples of Electromagnets in other equipment.
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.

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
Why are electric wires don-not made of rubber?
Obviously, rubbers are not conductors. Wires are commonly made of copper.
What is the metal used for electric wire?
Copper and aluminum used for electric wires
What material could be put around the wires to insulate an electric cable and a plug?
plastic or rubber
What metal is usually for wires in electric circuits?
copper as it is a good conductor of electricity :)
Which metal is used in electric wires commonly at home and why?
Copper Metal is used because it is good conductor of electricity
Why does a person wear rubber gloves while handling electric wires?
To prevent being shocked. Rubber is an insulator, and keeps electricity from flowing from the wire to you.
What robots are made of?
Mostly metal, sometimes plastic and sometimes rubber+metal or rubber+plastic. Sometimes all 3.
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.
