Question

How does the resistance of a wire depend upon its radius

Answer 1

Explanation:

• The resistance of any conductor is directly proportional to the length of conductor and is inversely to its area of cross section.

• From this we can conclude that resistance of wire is inversely proportional to the square of radius.

Answer 2

Answer:

The resistance of any conductor is directly proportional to the length of conductor and is inversely to its area of cross section. From this we can conclude that resistance of wire is inversely proportional to the square of radius.
