Question

Why are electric wire made of aluminium or copper?

Answer 1

Hi Guys!!

Cu has highest electrical conductivity and least resistance among all and is highly stable to heat.

And Al is lightest of all so it can be made into wires easily and its the cheapest metal among all.

So all these factors make these two best among all the metals to be used as wires to conduct electricity.

Answer 2

They are good conductor of electricity and have low resistivity.
