Question

Why are copper or aluminium wires generally used for electrical transmission and distribution purposes

Answer 1

Answer:

Copper and aluminium wiresare generally used for electricity transmission as they have low resistivity. Low resistivity decreases the resistance and hence increases the amount of current in the circuit. Therefore, they are good conductors of electricity.

Answer 2

Answer:

Because copper and aluminium are good conductors to transmit power and they are cheap too
