1. The problem statement, all variables and given/known data Given the circuit shown find: a) value of i_a b) value of i_b c) value of V_o d) power dissipated in each resistor e) power delivered by the 50v source Picture: (http://img197.imageshack.us/img197/4515/1000941y.jpg [Broken]) I am very new to circuits, any help would be much appreciated. 3. The attempt at a solution I understand how to do kcl and kvl and I understand ohm's laws, but I just can't seem to find out where to start. I've tried many things. And now I'm thinking it's how I'm assigning my passive sign convention. Do I even need to assign signs?! help please!
