What is the resistance per 1,000 feet of 8 AWG aluminum stranded conductors?

• A. 0.778 ohms
• B. 1.0 ohms
• C. 1.28 ohms
• D. 2.0 ohms

Answer: (C)

The resistance of conductors is a critical parameter in electrical installations, influencing the efficiency and safety of electrical systems. For 8 AWG aluminum stranded conductors, the standard resistance value is approximately 1.28 ohms per 1,000 feet. This value is derived from established electrical codes and industry standards that specify the electrical resistance characteristics of different sizes and types of conductors. Understanding the correct resistance is essential for applications such as calculating voltage drop, ensuring proper sizing of conductors, and maintaining the overall efficiency of an electrical system. The value of 1.28 ohms indicates that if current flows through these conductors over a distance of 1,000 feet, it will encounter a resistance of that amount, affecting the performance and safety of the electrical circuit. In contexts like electrical design and planning, having accurate data regarding conductor resistance allows engineers and electricians to make informed decisions about the materials and configurations for their projects.
