hi
The resistance of a wire is directly related to the cross sectional area, so the resistance will decrease as the diameter increases. When the diametr of the conductor increase, the area is increased, so, the resistance of the conductor is decrease. Since the electrons can pass freely through the conductror.
Doubling the radius increases the cross sectional area of the wire four times. As you can see in the picture if you increase the diameter of the wire then the resistance will decrease . ... As Resistance is Inversely proportional to the area of conductor.
