Copper has
less resistance than aluminium and has greater tensile strength than aluminium.
To work, copper proves an excellent material as compared to aluminium. In spite
of this, now a days aluminium is extensively used in transmission and
distribution of power supply because :
It is cheaper
than copper
Copper is not available
It is light
in weight
It is easily
available
It is cheaper
than copper
Copper has
less resistance than aluminium and has greater tensile strength than aluminium,
still now a days aluminium is extensively used in transmission and distribution
of power supply because aluminium is generally more inexpensive as compared to
copper-conductors.
Hence, the
correct option is (A).
