How Does The Resistance Of Wire Depends On Its Radius?

The resistance of a wire is inversely proportional to the cross-sectional area of a wire whereas, the cross-sectional area of a wire is directly proportional to the square of the radius of the wire.

Therefore, the resistance and the radius of the wire are inversely proportional to each other.

Therefore, as the radius increases, the resistance of the wire decreases. Therefore, the resistance of a wire depends on its radius.
