Question

Two copper wires of lenght l and l2 have radii r and 2r respectively. The ratio of their specific resistance is

Answer 1

Answer:

Ratio will be 1:1.

Explanation:

Specific resistance is a property of material and unlike resistance is does not depend upon the length and area of the wire. All the wires made from the same material ( in this case copper) will have same specific resistance regardless of their length and area.
