Difference between positive and negative flow in wires

John1397

Does anyone know if I run 12 volts dc at 1 amp power for a distance of 250 feet and one wire is 12 gauge used for positive and other negative wire is 20 gauge will the smaller ground wire affect what the positive wire can carry?

It won't affect what the larger wire is able to carry but the smaller wire will be the bottleneck. It wouldn't matter how large the bottle gets if the neck is small. The neck is what prevents the ketchup from running. Understand?

The current in the whole circuit will be determined by the overall resistance
