Final answer:
The resistance of 1,500 ft of #6 uncoated stranded copper wire is approximately 0.764 ohms in a DC circuit.
Step-by-step explanation:
To find the resistance of a wire, we can use the formula R = (ρ * L) / A, where R is the resistance, ρ is the resistivity of the material, L is the length of the wire, and A is the cross-sectional area of the wire.
In this case, the wire is made of uncoated stranded copper, which has a resistivity of about 1.7 x 10^-8 ohm-meter. The cross-sectional area of #6 wire is approximately 13.3 mm². So, let's calculate the resistance:
R = (1.7 x 10^-8 ohm-meter * 457.2 meters) / (13.3 mm² * (1 mm/1000 mm)²)
R ≈ 0.764 ohms
