![]() These complexities are not too significant so long as we remember that in practice, current flows in both directions in an AC circuit (hence the term alternating current). It is also the designated return path for the power lines, though, in real life, AC is quite a bit more complicated than "in" and "out" current. Neutral is so-named because it is at a nominal voltage of 0V. In this case, the nominal voltage is around 120V (volts), but this varies by region. In practice, the hot wire is responsible for carrying the voltage appliances need to function. With that in mind, the standard convention dictates that AC circuits contain three main wires: "Hot" or "Live", "Neutral", and "Ground". We will also be using the North American electrical standards, but note that the concepts apply everywhere, with the main difference being naming and wiring conventions. In most places in the world, residential electrical systems use Alternating Current, so that's what we will focus on today. The names we use to describe these power lines vary based on the region and whether we are talking about a Direct Current (DC) circuit or an Alternating Current (AC) circuit. No Neutral Wire?
