[QUOTE="kme, post: 25600, member: 113"] :_| Whichever way you read that question Admin, I`m afraid that a quarter is not, and cannot be correct.Blushing If the conductor has a resistance of 0.25........ As Paul says, doubling its length will double its resistance = 0.5 OR halving the csa will similarly double its resistance = 0.5 ergo: doing both will produce both effects together-0.25 x 2 = 0.5 x 2 = 1 ok????
