Question

Among coal and aluminum which one is used to make electric wires and why?

Answer 1

Explanation:

Aluminum provides a better conductivity to weight ratio than copper, and therefore is also used for wiring power grids, including overhead power transmission lines and local power distribution lines, as well as for power wiring of some.

Answer 2

Aluminum is used to make electric wires.

Explanation:

• Aluminum is said to be the preferred material used in electrical transmission and distribution.
• They are used in making wires because of their low resistance and high conductivity.
• It has superior conductivity to the ratio of weight in the metal. It is used in buildings, appliances, and aircraft purposes.
• Aluminum is also used for thermal conductivity
• Has it passes efficient current, it is also used for large power systems and for large transmission lines.
