1. The problem statement, all variables and given/known data Find Norton current and impedance between points A and B. 2. Relevant equations 3. The attempt at a solution I really dont have idea how to find impedance when points A and B are positioned like that in the diagram. And if lets say I found the impedance , when trying to look for Thevenin voltage(I dont really like norton, I always try to find U_th, speaking of it, when exactly should I use Norton instead Thevenin?), I found that Ut=0, but I don't if that's correct, neither if way of finding it was correct.
