What resistance does the 18 AWG power extension wire exhibit per foot?

• A. 0.002 ohms
• B. 0.0062 ohms
• C. 0.01 ohms
• D. 0.005 ohms

Answer: (B)

The resistance of an 18 AWG power extension wire is approximately 0.0062 ohms per foot. This value is derived from standard wire resistance tables that outline the resistance for various American Wire Gauge (AWG) sizes. In practical applications, understanding this resistance is crucial for calculating voltage drop and ensuring efficient power delivery in electrical circuits. The choice of 0.0062 ohms aligns with established electrical engineering standards for this wire gauge, making it the most accurate figure among the provided options. Other gauge sizes exhibit different resistances, which further emphasizes the significance of selecting the appropriate wire for specific applications to maintain safety and performance.
