Detailed Solution

The above statement is True.
According to the resistance formula
R =ριA
Where ρ = Resistivity
             ι = length of wire
           A = wire’s area of cross-section
For a thicker wire area, the cross-section would be larger since the resistance of a wire is inversely proportional to the area of the cross-section. The resistance of a thicker wire is less than that of a thin wire.Therefore, the current will flow easily in the thicker wire than in the thin wire of the same length.
