Detailed Solution

The above statement is True.
The opposition to the flow of electrical current through a conductor is characterised as resistance. The resistance of an electric circuit can be numerically measured. Electrical resistance is related to conductor length (L) and inversely proportional to cross-sectional area (A) and resistivity. Therefore, it can be expressed as

R = \frac{ρl}{A}

. The following factors determine the conductor's resistance:
The conductor's temperature.
The conductor's cross-sectional area.
The conductor's length.
Conductor's nature
