Length, thickness, temperature.
Explanation: For a given material R = ρ·L/A, so resistance increases with length (L) and decreases with cross‑sectional thickness/area (A). The resistivity ρ depends on temperature, so temperature changes resistance. Voltage and current do not determine intrinsic resistance (they only relate by R = V/I).
