A graphite rod is 1.0 m long, with a 1.0 cm by 0.5 cm rectangular cross sectional area. What is the electrical resistance between its long ends? What must be the diameter of a circular 2.0 m long copper rod if its resistance is to be the same?
We are not going to do your work for you. Somehow, you mistook Homework Help for do my work for me.
