Question

Give scientific reason. for electric power transmission copper or aluminum wire is used​

Answer 1

Answer:

for electric power transmission copper or aluminium wire is used because it provides low resistance in the flow of current through them.

And there will be less power used in overcoming resistance.

Answer 2

Answer:

Copper wire is more preferable but aluminium is also used

Explanation:

cooper's resistivity is less than that of aluminium. Therefore, current can easily flow through copper wire. Silver has least resistance but it's expensive after which cooper's resistivity is there and at 3rd it's aluminium
