An #18 AWG wire has a smaller diameter than a #10 AWG wire. Is this statement true or false?

• A. True
• B. False
• C. Depends on the material
• D. Not applicable

Answer: (A)

The statement is true. The American Wire Gauge (AWG) system is a standardized wire gauge system used to denote the diameters of round, solid, nonferrous, electrically conducting wire. In this system, a lower gauge number corresponds to a larger diameter of wire. Therefore, #10 AWG wire has a larger diameter than #18 AWG wire. This relationship holds true across the AWG standards, meaning that as the gauge number decreases, the wire diameter increases. The physical size difference impacts the wire's capacity to carry electrical current as well as its resistance, making it relevant in various applications in electrical systems. Understanding this gauge system is crucial for making appropriate choices in electrical installations and applications.
