1. The problem statement, all variables and given/known data Hi everyone! I'm trying to find the thevenin equivalent for part A of this circuit: http://imgur.com/4Jdg8w8 2. Relevant equations 3. The attempt at a solution I first remove part B, that is, open circuit it entirely. Then I try to find Voc across the two terminals that are open. I can see that the 47 Kohm is in series with the 18 Kohm since no circuit flows to the open circuit, and that the 15,000 Kohm is in series with the 33,00 Kohm. However I'm having a lot of trouble redrawing the circuit. Not really sure about how to make it look simpler.
