Copper combines several properties that have traditionally made it preferred for most electrical wiring. Copper is a good electrical conductor, provides a good contact surface, is ductile (is easily bent repeatedly without breaking) and it is not too expensive.
Aluminum is cheaper, lighter, softer, and therefore easier to bend than copper but is less desirable because it expands and contracts more than copper and produces loose connections. Many houses were built in the US in the 1970s with aluminum but most of them burned down. Aluminum is no longer allowed in houses in the US except for service entrance conductors. In commercial and industrial installations aluminum is still allowed but connections are required to be re-torqued once a year. That is quite a labor-intensive project. -- Sparkfighter

Which is a better conductor of electricity copper or silicon?
Silicon is only a semiconductor. Copper on the other hand is used to make wires and is an excellent conductor of electricity.
Why can't copper produced by displacement used for electrical wires?
Copper is not a good conductor of electricity. The electric wires could not be made of copper because of its poor conduction with electricity.
Does copper wire produce electricity?
Yes. Copper is a very popular material used to make electrical wires.
What can pure copper be used for?
Pure copper is used for electrical wiring. Pure copper conducts electricity better than impure copper.
Why copper wires are used in householding wires?
It's because copper is the best conductor of electricity, other than silver which is slightly better but too expensive.

What element is used for wires that carry electricity?
Copper
Why can't copper produced by displacement used for electrical wires?
Copper is not a good conductor of electricity. The electric wires could not be made of copper because of its poor conduction with electricity.
Why is copper used for telephone wires?
Copper is used for telephone wires because it is the second best conductor of electricity after silver (which is a little pricey).
Does copper wire produce electricity?
Yes. Copper is a very popular material used to make electrical wires.
Metal that is often used in wires that conduct electricity?
i was thinking copper
Metal often used in wires that conduct electricity?
Copper is the most common.
What can pure copper be used for?
Pure copper is used for electrical wiring. Pure copper conducts electricity better than impure copper.
What is copper And what is three uses of a copper?
copper is a metal in the periodic table of elemets because its a pure metal copper is used to make wires because its a good conductor of electricity its also used in parts of boats and also as jewelry
What metal is usually used for wires in electric circuit?
Generally copper, because it is cheap and also conducts electricity.
Why is steel not used for electric wires?
Because steel is not a good conductor of electricity. Copper is the best conductor for electricity.
Is copper an insulator or a conductor?
It is a very good conductor. It is used in wiring to deliver electricity.
