🔍 Key Concepts

• American Wire Gauge (AWG) system and what the numbers represent • Relationship between gauge number and wire diameter • How cross‑sectional area changes when diameter changes

💭 Think About

• As the AWG number increases, what happens to the physical size (diameter) of the wire? • Does a smaller diameter wire have a larger or smaller cross‑sectional area? • Order the choices from thickest to thinnest wire, then pick the one with the smallest area.

✅ Before You Answer

• Confirm that in the AWG scale, larger numbers mean smaller wire diameters • Remember that cross‑sectional area is directly related to the wire’s diameter (thinner wire = smaller area) • Before choosing, mentally rank gauges 12, 14, 16, 18 from largest to smallest diameter and then select the smallest diameter
