Question

There are two wires of the same length and of the same material and radius r and 2r. The ratio of their specific resistance is

Answer 1

Answer:

ratio of their specific resistances would be 1:1.

Explanation:

It is because specific resistance is a property of material and unlike resistance does not depend upon the area or length of wire. So all the wires made from same material will have same specific resistance regardless of their area or length.
