In introductory circuit analysis, which wire gauge (American Wire Gauge, AWG) will typically carry the most current safely (all else equal, such as material and length)?

• A. 30 AWG
• B. 18 AWG
• C. 22 AWG
• D. 10 AWG

Answer: (D)

Verified step by step guidance

1. Understand that American Wire Gauge (AWG) numbers are inversely related to the wire diameter: a smaller AWG number means a thicker wire.
2. Recall that thicker wires have lower electrical resistance and can safely carry more current without overheating.
3. Compare the given wire gauges: 30 AWG, 22 AWG, 18 AWG, and 10 AWG, noting that 10 AWG is the thickest among them.
4. Recognize that because 10 AWG wire is thicker, it has a larger cross-sectional area, which allows it to carry more current safely compared to the others.
5. Conclude that, all else being equal, the 10 AWG wire will typically carry the most current safely.
