WebOct 18, 2024 · If you powered your wires with a constant voltage source (such as a 12v power supply), than the wire with less resistance will draw more current and get hotter … WebA 12-gauge wire is wider than 14-gauge wire and thus has less resistance. The lesser resistance of 12-gauge wire means that it can allow charge to flow through it at a greater rate - that is, allow a larger current. Thus, 12-gauge wire is used in circuits which are protected by 20-Amp fuses and circuit breakers.
