1. The problem statement, all variables and given/known data I have to find V0 and I0. [PLAIN]http://img842.imageshack.us/img842/3058/resistor.png [Broken] 2. Relevant equations I am having trouble identifying parallel resistors. 3. The attempt at a solution So far I think that the 70 ohm and 30 ohm resistors are parallel but I am not sure. I know the share the same node at the top but don't they also have to share the same node as the bottom? Which is not the case (I don't think) due to that middle line that separates the top two resistors from the bottom two. I just need to know if those are parallel.
