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

The current will flow more easily through thick wire. It is because the resistance of a conductor is inversely proportional to its area of cross-section. If thicker the wire, less is resistance and hence more easily the current flows.
