Does the size of the neutral affect resistance limiting current flow?

Current is set by the circuit’s total impedance, and the neutral is part of that return path. The resistance of the neutral adds to the overall resistance. A larger (thicker) neutral has lower resistance, reducing voltage drop and allowing current to flow more freely for a given load; a smaller neutral has higher resistance, increasing the return-path drop and tending to limit the current. This concept applies to both AC and DC systems, regardless of conductor material (aluminum or copper) — the key idea is that conductor size affects resistance and thus how much current can flow.
