WebSolution. Verified by Toppr. Resistance of wire is given by R= AρL. where L is the length of wire and A is the cross-section of wire. So resistance of wire depends directly on the length of wire and inversely on cross-section of wire. WebThe resistance of a wire is inversely proportional to the area of cross section of the wire. Since the area of the cross section of wire is proportional to the square of radius, the resistance of the wire is inversely proportional to square of the radius of the wire. Hence, the resistance of wire decreases as the diameter of the wire increases ...
