Question

Why electric power transmission , copper or aluminum wire is used.​

Answer 1

Explanation:

For electric power transmission, Copper or Aluminium wire is used because they provide low resistance path to the flow of current. Thus, the power loss in the low resistance transmission wire will be less.

Answer 2

Answer:

(1) Copper and aluminium are good conductors of electricity. (2) Copper and aluminium have very low resistivity. Hence, when an electric current flows through a wire of copper or aluminium, heat produced is comparatively low. Therefore, for electric power transmission, copper or aluminium wire is used.
