why are electric wires made of copper?

Hi Manish,

Copper is a good conductor of electricity, which is a prime requirement.

At the same time it is also highly ductile (i.e.easily can be made into wires).Copper is readily available due to which it is not very expensive.

That is why electric wires are made of copper.

@athmikas and eph: very good answers keep it up!!
