Which of the statements below is true?

The statement that an 8 AWG conductor has a greater resistance per foot than a 6 AWG conductor is true based on the principles of electrical conductivity. The American Wire Gauge (AWG) standard determines the sizes of electrical conductors, with lower gauge numbers indicating larger diameters.

As the gauge number increases, the diameter of the conductor decreases, leading to an increase in electrical resistance. This is because a smaller diameter conductor has less cross-sectional area available for electrical current to flow through, resulting in higher resistance. In essence, a 6 AWG conductor, being larger in diameter than an 8 AWG conductor, will have a lower resistance per foot compared to the 8 AWG conductor.

Consequently, when comparing the two sizes, it's evident that the 8 AWG conductor has a higher resistance per foot, making the statement true. Understanding this concept is crucial for anyone involved in electrical work, as it directly impacts circuit design, safety, and efficiency.
