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

Explanation

The current will flow more easily through a thick wire than through a thin wire of the same material and having the same length when connected to the same source.
Because, the resistance of a wire is inversly proportional to its area of cross-section. A thick wire has more area of cross-section and hence less resistance compared to a thin wire provided the two wires have the same length.
Hence, a current can flow more easily through a thick wire compared to a thin wire when connected to the same source.
