# Wire Resistance

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.

• Yes it is incorrect. – Brian Drummond Aug 7 '16 at 15:23
• Draw the diagram of the battery, the wire and the load. Then work it out again. – Transistor Aug 7 '16 at 15:28
• To clarify, your math isn't wrong, but your visualization of the problem is. – Ignacio Vazquez-Abrams Aug 7 '16 at 15:29
• Remember, a circuit is a closed loop. Sketching the circuit will likely help. Look at everywhere the #10 wire is required in the circuit. – user2943160 Aug 7 '16 at 15:41
• @DanielTork, all of the people who commented before you already know that. Since this is school work, they are trying to lead the OP to the answer without just spelling it out. We generally try to help people with school work, but avoid just coming out and telling them. Not a big deal. Just FYI. ;-) – mkeith Aug 8 '16 at 3:49
