1. The problem statement, all variables and given/known data Find the Thevenin equivalent of the circuit shown below 2. Relevant equations Nothing but basic principles 3. The attempt at a solution Alright, I realize that it will take some time for the attachement to be approved, but it's a really simple circuit. It has just one loop. Starting from ground, you go up through a 10 V voltage source, across a 1k resistor in series with it, and then back down to ground through a "controlled" current source, which means going in the opposite direction of the current indicated by the arrow ('up'). Note that it is a controlled source, even though it doesn't look like it in the diagram. This is because Circuit Maker is mildly retarded and doesn't represent controlled sources using diamonds, but using some other much more complicated circuit symbol. So I just threw an independent current source in there. Anyway, the output voltage is taken to be across this branch (the current source). Anyway, the current across the 2k is ix, and the current supplied by the dependent source is 3ix. I realize I haven't done anything towards a solution yet, but that's because I'm having conceputal difficulty with the controlled source here. So to be fair, for the time being I won't ask for help with how to solve it except to ask, "what do I do with the controlled source when I am trying to calculate the Thevenin equivalent voltage and resistance?"
