How, from the point of view of parallel connection of resistors, to explain the dependence of the resistance of a homogeneous wire on its cross-sectional area?
You can think of a conductor as several conductors of the same cross-section connected in parallel. The resistance of a conductor is inversely proportional to its cross-sectional area. The inverse total resistance is equal to the sum of the inverse resistances of each conductor. Therefore, the total resistance will be inversely proportional to the sum of the cross-sectional areas of each conductor.
