You’re comparing two copper conductors. Both have the same wire size and are at the same temperature, but one is 50 feet long and the other is 100 feet long. How does the resistance of the 100-foot conductor compare with the 50-foot conductor? A. Half as much resistance. B. The same resistance. C. Twice as much resistance. D. Four times as much resistance. 👇 What’s your answer—and why? Bonus: Why might conductor length matter when supplying equipment a long distance from the panel? Answer and explanation tomorrow! ⚡
