To determine the resistance of 175 feet of 14 AWG stranded uncoated copper conductor, we can use standardized resistance per unit length values for copper wire. The resistance of copper wire is typically calculated using a specific figure, which for 14 AWG wire is approximately 2.525 ohms per 1000 feet at room temperature.

First, we can figure out the resistance per foot for 14 AWG copper:

[ \text{Resistance per foot} = \frac{2.525 , \text{ohms}}{1000 , \text{feet}} = 0.002525 , \text{ohms per foot}. ]

Next, we calculate the total resistance for 175 feet:

[ \text{Total Resistance} = 0.002525 , \text{ohms/foot} \times 175 , \text{feet} = 0.442375 , \text{ohms}. ]

However, it’s crucial to understand that the resistance can slightly vary based on factors like temperature and the exact characteristics of the copper alloy used in the wire. Using standard values, the calculated resistance can be approximated to common resistance values for practical applications.
