Which wire gauge size has the largest diameter?

• A. 20
• B. 22
• C. 24
• D. 18

Answer: (D)

The wire gauge size with the largest diameter is indeed the 18 gauge. In the American Wire Gauge (AWG) system, the gauge number is inversely proportional to the wire diameter; as the gauge number decreases, the diameter of the wire increases. Therefore, an 18 gauge wire is thicker than a 20, 22, or 24 gauge wire. This is important because thicker wires (lower gauge numbers) can carry more current and are generally better for applications that require higher power transmission, while thinner wires (higher gauge numbers) are more suitable for low-current applications. Understanding wire gauge sizes and their implications is crucial for safe and effective wiring in electronic and electrical projects.
