Answer Posted / praveen
here i think the question is asked considering the same
current is flowed by the wires.
we should consider the fact that in
aluminium the tensile strength is more. conductivity is
less but cost is also less.
so the span of aluminium is high. also the conductor size
is more. but even in that case the overall cost is less for
aluminium.
