Gold or silicon may be the metal most popular for use in electronic circuits. Gold because it does not corrode in the atmosphere and silicon because it is used to make semi-conductors.

A lot of gold is used for fine wires and contacts... Silver and copper quickly oxidise (also called "tarnish") if exposed to the atmosphere so are not used as much despite their very good conductivity which is almost as good as gold.

but the most common are copper (nicest combination of conductivity and cost),
silver (a better conductor),
gold (where tarnishing is a no-no)
aluminum (light wight).

For the contacts, nickel-gold finishing, palladium finishing

Why electric wires are covered with insulator?
If electric wires weren't covered with insulation, there would be short circuits.
WHY do the connecting wires used in electric circuits not produce any heating effect?
because of its covering.
Hot wires in home wiring are normally colored and ground wires in computers are normally colored?
Hot wires in home are normally colored black. And ground wires in computers are normally colored black as well.
What is a load side of the panel?
It is where the black wires are connected for branch circuits.
What polarities red wires and black wires indicates in case of dc measurement?
In typical DC circuits, Red = Positive, Black = Negative.
What metal is usually for wires in electric circuits?
copper as it is a good conductor of electricity :)
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 electric wires are covered with insulator?
If electric wires weren't covered with insulation, there would be short circuits.
How are circuits made?
circuits are made by connecting wires to an electrical resource and the electricity travels through and powers your electric device.
What is the metal used for electric wire?
Copper and aluminum used for electric wires
WHY do the connecting wires used in electric circuits not produce any heating effect?
because of its covering.
Which metal is used in electric wires commonly at home and why?
Copper Metal is used because it is good conductor of electricity
Why are copper wires and not steel wires used in electric circuits although both are copper and steel are electoral conductors?
copper is cheaper to manufacture and easier to bend then steel
Why are electric wires made out of metal instead of rubber?
Metal is a very good conductor of electricity. Rubber doesn't conduct electricity.
Why does the electric wire become loose in summers?
The metal wires expand in the heat - making them sag.
What are five uses of copper in Latin America?
Copper fittings, electromagnets, electric wires, lead-free solder (alloyed with tin), integrated circuits.
Are all electric wires in a house metal?
Yes. Conducting carbon and plastic cannot cope with the current.
