What happens to resistance as the diameter of a conductor increases?

Explanation:
Resistance depends on how much cross-sectional area the conductor has. For a given material and length, resistance is R = ρL/A, so as the diameter—and thus the cross-sectional area A—increases, the resistance decreases. A concrete example: doubling the diameter makes the area four times larger, so the resistance becomes one quarter. Therefore, increasing diameter leads to a decrease in resistance.
