Which statement is true about AWG sizing?

Which statement is true about AWG sizing?

• A. Higher gauge means larger conductor
• B. Higher gauge means smaller cross-sectional area
• C. Gauge has no effect on cross-section
• D. Gauge and cross-section are independent

Answer: (B)

In AWG sizing, the number on the wire is inversely related to its physical size. As the gauge value increases, the conductor’s diameter gets smaller, which also reduces its cross-sectional area. This inverse relationship means higher gauge wires are thinner and carry less current than lower gauge wires. So the true statement is that higher gauge means smaller cross-sectional area. The other ideas don’t fit because changing the gauge number directly changes the diameter and cross-sectional area, and they are not independent or size-neutral.
