1. In the case of a current source in series with a resisitor, can this be transformed to just a current source with 0 resistance, or is the resistance infinity in the Norton equivalent? 2. Relevant equations 3. The attempt at a solution My teacher told us this in class but i cant remember if a current source w/ resistor in series is same as 0 current or infinity current. And is the answer the same for the equivalent norton resistance?
