1. The problem statement, all variables and given/known data Find thevenin equivalent of resistor circuit 2. Relevant equations 3. The attempt at a solution This may be a dumb question, but does a thevenin equivalent NEED to have a voltage source? On my final exam there was a question that asked for the thevenin equivalent of a circuit that was only resistors. Finding the thevenin resistance was no problem so I just put that resistance in series with a 0V voltage source. Can the thevenin equivalent be just a resistor?
