A load is located 100 feet from the source. If #10 copper wire supplies the load, the total resistance of the wire between the source and the load will be ? #10 copper wire at 1,000 feet is 1.21 ohms. My answer is .121 ohms. But, I was told that was incorrect.
Thank you all. It appears that I have not included the return wire to complete the circuit. This problem was for a DC circuit, and all I was picturing in my mind was the typical light for an automobile with only one lead coming off it, using the chassis as the ground. I am going with .242 ohms to include the return path.
