Answer Posted / vinod
---> Copper (Cu) was a good CONDUCTOR (good conductivity) than
Aluminium (Al).
---> Al is cheaper than cu
---> Earthing was done because of excess of electrons passes
through the Equipment/Device hence the device was damaged. So
Earthing prevents equipments from (excess of
electronics)damage.
