so yea, 2nd year ee class, quick unit on opamps. not to bad so far.
However the textbook dumps the equivalent circuit diagram (first attached image) for an op amp on me, and...it makes no sense, because what the heck Is that set of triangular branches doing. proff's pulled out a similar diagram. For abit I've just been assuming i'm missing something and figure i'll get around to working it out
today we get a set of example problems, a diagram from one of which in is the 2nd attached image. In it there's a circuit with an op amp and the equivalent circuit. What's going on there makes perfect sense. It also has very little relation to the equivalent circuit in the first image.
I'm assuming that triangular set of branches in the first image, aren't actually branches at all, that they've used that triangle to block out what's inside and outside the device, and for some reason they've decided to make the lines the same colour and width as the lines denoting the actual branches? Am I in the ballpark here?
