$(a)$ Why are copper and aluminium wires usually employed for electricity transmission?
(N/A) Copper and aluminium are metals that possess very low electrical resistivity,which means they offer minimal resistance to the flow of electric current.
Because of this property,they act as excellent conductors of electricity.
Consequently,they are widely used in electrical wiring and transmission lines to ensure efficient power delivery with minimal energy loss as heat.
