Answer:
More collisions mean more resistance. Second, the cross-sectional area of the wires will affect the amount of resistance. Wider wires have a greater cross-sectional area. ... In the same manner, the wider the wire, the less resistance that there will be to the flow of electric charge.

Inversely proportional
Explanation:
Resistance of a wire is inversely proportional to its cross sectional area. More the cross sectional area less is the resistance and vice versa
