Which of the following statements about copper wire sized by the AWG rating system is correct?

Question 1 of 27070

Which of the following statements about copper wire sized by the AWG rating system is correct?

🔍 Key Concepts

• American Wire Gauge (AWG): how the gauge number relates to the physical size (diameter) of the wire • Relationship between wire diameter, resistance, and current-carrying capacity • What properties like dielectric strength actually depend on (conductor vs. insulation)

💭 Think About

• Think about whether a higher AWG number means a thicker or thinner wire, and how that affects resistance. • Ask yourself: does more resistance per 1000 feet occur in a larger or smaller diameter conductor made of the same material at the same temperature? • Consider which properties are determined by copper size and which are determined mainly by the insulation material around the wire.

✅ Before You Answer

• Be clear on whether AWG number increases or decreases as wire size gets larger. • Compare what happens to resistance per 1000 ft when the cross‑sectional area of the wire changes (same metal, same temperature). • Check whether dielectric strength is a function of the copper conductor or the insulation around it.
