Q: The resistance of a coil of wire is 6.2ohms and its length is 1.0m. Using only 1.0m lengths from the same reel, without cutting any of them, state how you would produce a resistance of
(i) 3.1ohms
(ii) 12.4ohms
so confused! Do you increase/decrease turns of coil or connect them in series and parallel?
