SUMMARY
The discussion clarifies that when running 12 volts DC at 1 amp over a distance of 250 feet, using a 12-gauge wire for the positive and a 20-gauge wire for the negative, the smaller 20-gauge wire will act as a bottleneck. The current capacity of the circuit is determined by the wire with the smallest gauge, which in this case is the 20-gauge wire. Therefore, the 12-gauge wire will not be able to carry more current than what the 20-gauge wire allows due to its higher resistance.
