http://img295.imageshack.us/img295/6016/55877904.th.jpg [Broken] I tried everything to solve this. XL and XC are an inductor and a capacitor (respectively). I start with the idea that there are 50 V on each of them, and that a current of 5 A flows between, and that the generator has no effect, because the potential on each end is the same. But I can't figure out what current the ampermeter shows. The right answer is 2,5*sqrt(2), but i can't get it... tryed to replace the LC tree with a current generator, (duno how stupid the idea is) and everything else that came to my mind...but I just don't know the trick.
