Question

Electric wires are made up of copper why?

Answer 1

Hint: We consider not only the conducting property of metal while constructing conducting wires, but also other features such as oxidizing property in the presence of air, heat resistance property, and so on. The metal used to conduct wires must also be cost-effective.

Complete answer:
The term "conducting wire" refers to a metal conductor that is used to transport electricity over a long distance.
Following are the reasons why electric wires are made up of copper:
Copper is a good conductor of electricity which implies it has low resistance.
Copper also has a lower oxidative potential than other metals. When oxygen and moisture in the air react with the surface of a metal, oxidation occurs. Like rust on steel, this process corrodes the metal and leaves a film-like coating. Copper does not rust and instead develops a greenish patina known as copper oxide. Unlike rust, however, this coating protects the metal from future corrosion while also allowing it to conduct electricity.
Copper is less expensive than other metal conductors. As it will not be affordable for everyone, the metal chosen should be reasonably priced.
Copper is highly ductile and can be drawn into thin wires easily.
Copper is resistant to heat compared to other metals.

Note:
Silver is known as the best conductor of electricity but still, copper is preferred over silver as copper is cheaper and cost-efficient than silver. Other than copper, electric wires are made up of aluminum.
