Hi guys, I have a question that is nagging me quite a lot. Let us say that we have a circuit who has two independent sources (any combination of voltage and current sources). In the determination of Vth, can we choose whether or not to use superposition to find this Vth? Because my understanding was that you could use superposition to simplify the analysis or choose to leave both the sources in and find the equivalent voltage. Am I correct? Thanks guys :).
