Answer:
Copper is preferred over aluminium for home electric wires because it transmits load more easily and has a more stable electrical conductivity. (option d)
Explanation:
- Copper is preferred over aluminium because it is easy to use and conducts electricity more effectively.
- They are more stable and durable.
- Its tensile strength is 40% better than aluminium. Therefore, chances of breakage is less compared to aluminium wires.
- It has lower thermal energy. Therefore, it doesn't expand with the exposure to heat like aluminium.
- Copper is stronger than aluminium.
- It carries twice the current of aluminium.
