The resistance of a conductor depends on the:
Length, area of cross-section, material of the conductor, and temperature
The resistance of a conductor is given by \(R = \rho \dfrac{L}{A}\), where L is the length, A is the area of cross-section and \(\rho\) is the resistivity of the material.
Resistance is directly proportional to length and inversely proportional to area of cross-section, and resistivity itself depends on the nature of the material and changes with temperature.
Voltage and current do not determine resistance; by Ohm's law R is the fixed ratio V/I and stays the same even when V and I change together.
"Length and area only" is incomplete, as it ignores the material and temperature.
Hence, resistance depends on length, area of cross-section, material of the conductor, and temperature.
