Question

Give a scientific reason:

For electric power transmission, copper or aluminium wire is used.

Give Reasons
Advertisements

Solution

  1. Copper and aluminium are excellent electrical conductors.
  2. Since the resistance of copper and aluminium is very low, the amount of heat generated while carrying an electric current through them is also low.

Therefore, copper or aluminium wires are used for electricity transfer.
