Question

People prefer Copper to Aluminium wiring for electrical supply at homes. Which might be the possible

reason for the preference of Copper to Aluminium?

(i) Aluminium wiring is expensive

(ii) Aluminium is better conductor of electricity than Copper

(iii) Copper transmits loads easily

(iv) Copper is more stable in electrical conductivity

(a) (i) & (ii)

(b) (i) & (iv)

(c) (ii) & (iv)

(d) (iii) & (iv)​

Answer 1

People prefer Copper to Aluminium wiring for electrical supply at homes as (iii) Copper transmits loads easily and (iv) Copper is more stable in electrical conductivity.

• The correct option is (d) (iii) & (iv)​
• Copper is a good conductor of electricity and is less expensive than other metals.
• Aluminum wiring is majorly used for electrical installations. Since copper cabling is typically safer and performs better electricity efficiently, however, it is preferred over aluminium.
• Copper is more stable in electrical conductivity as well.
• Thus, more people prefer copper cabling over aluminum when they cable or install a new electrical system in their homes.
