Hello. The question appears not to complex! however im been on break (and still am haha) but I saw this in an old exam paper and its bugging me that I dont know how to do it! heres the question; http://img59.imageshack.us/img59/9868/dfdfmu.jpg [Broken] Kirchhoff voltage law comes to mind. However im confusing myself. I thought that the current across each resistor in one of the closed loops cant be the same? or can it? anywhos ignore my little rant. Id really appreciate if somone could explain to me the answer cheers.
