Detailed Solution

The above statement is True.
According to the resistance formula

\Rightarrow R = \frac{ρι}{A}

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.
