I've been analyzing a lot of circuits lately, and I've noticed that they sometimes have resistors in the supply line in between stages, like in this metal detector circuit from talkingelectronics.com:
the 330R resistor on top is what I mean. I've seen it in transistor amplifiers as well. What effect does this have on the circuit? I feel as though it would make the analysis much more complex, with voltage drops and all. Can somebody shed some light for me? It would be much appreciated. Thanks in advance
