What is the resistance of 1000 feet of #10 copper wire?

• A. 10 Ohms
• B. 5 Ohms
• C. 1 Ohm
• D. 0.1 Ohm

Answer: (C)

To determine the resistance of 1000 feet of #10 copper wire, it's important to know the resistivity of copper and how the wire gauge relates to resistance. The resistance of a conductor can be calculated using the formula: \[ R = \rho \frac{L}{A} \] where \( R \) is resistance, \( \rho \) (rho) is resistivity, \( L \) is the length of the wire, and \( A \) is the cross-sectional area of the wire. For #10 copper wire, the resistance is typically around 1.24 ohms per 1000 feet. In practical use, this value can be approximated to 1 ohm for ease of calculations. Given that the length is specified as 1000 feet, it directly correlates to the standard resistance measurement for this specific gauge of wire. Therefore, selecting 1 ohm indicates an understanding of the resistance value associated with this copper gauge, confirming that the correct answer is indeed 1 ohm.
