Silver is the best conductor but copper is used because silver is too expensive.
Copper is used for telephone wires because it is the second best conductor of electricity after silver (which is a little pricey).
No, copper is commonly used to make wire.
It's because copper is the best conductor of electricity, other than silver which is slightly better but too expensive.
Out of all the common metals copper is the best electrical conductor. Only silver is slightly better.
Copper and aluminum are good conductors. Other conductors like silver aren't used to make electric wires because copper and aluminum are cheaper but have the same properties.
Wires are made of copper and sometimes coated with silver for use at frequencies above 1 GHz. Wires used on overhead power lines are usually stranded aluminimum with inner strands of steel.
For wiring, we only use copper and silver. The most common conductor is copper. Almost all wires use copper as a conductor.
Silver is the best electrical conductor in the periodic table, next is copper. Copper is used in wires because it is nerly as good as silver, but is far cheaper.
Silver is not used for electrical wires mainly for two reasons. Silver is too expensive to use and it is a soft metal which is not suitable for electrical wires.
Of all the metals copper is the best conductor of electricity apart from silver which is slightly better but a lot more expensive.
Even though silver is the best conductor of electricity, it is extremely expensive. Thus silver is not used to make electical wires. Silver is also very soft to be used as electric wires.
I think copper is cheaper.
