Question

Will current flow more easily through a thick wire or a thin wire of the same material, when connected to the same source? Why?

Answer 1

The resistance of a conductor is inversely proportional to its area of cross-section. A thick wire has a greater area of cross-section whereas a thin wire has a smaller area of cross-section. Thus, a thick wire has less resistance and a thin wire has more resistance. Therefore, current will flow more easily through a thick wire.
