In terms of AWG wire size, what does a larger number indicate?

In American Wire Gauge (AWG), a larger number indicates a smaller wire size. This numbering system is somewhat counterintuitive; as the gauge number increases, the diameter and cross-sectional area of the wire decrease. For example, 20 AWG wire is thinner than 18 AWG wire. This system is widely used in the United States and provides a standardized way to refer to the size of electrical conductors. Understanding this concept is important for anyone working with electrical wiring, as it affects current-carrying capacity and resistance in circuits.
