Question

6. Why copper or aluminium wires are used in electricity transmission?

Answer 1

Copper or aluminium wires are used in electricity transmission because-

• They are ductile and hence can be easily drawn into wires. It is repellent to corrosion also.
• They are good conductor of electricity and have low resistance.
• This allows them to pass the current through them.
• Copper and aluminium are excellent electrical conductors and their wires are commonly used for electrical transmission.
