Homework Statement http://www.chegg.com/homework-help/questions-and-answers/ideal-opamp-find-v0-terms-vs-need-help-solving-vp-firstly-understanding-parts-q8278769 Homework Equations I am having difficulties with this problem. It asks to find vo in terms of vs. For the gain, I got an...

look at this picture from my book. In this example, what you said is correct, the assumed direction of current affects the sign. But on the other picture that i posted, they are not doing this. I think they are using a counterclockwise loop for the lower left loop in the other picture, but...

but if a keep the negative answer, I get a different result?

I just noted something. Does the direction of the current affects the signs (+ or -)? For example, if i have a KVL with a loop going clockwise, and when it reaches a resistor, that has a current going in the opposite direction (to the left), does that matter? If a kvl with a loop going...

I end up with a circuit in series with three resistors, a 15ohm, and the 3ohm and the 2ohm. So is it 20? I read somewhere that when a resistor is not connected to the circuit, it can be ignored, so why is this not the case?

aaa so starting from the lower right node, it would be 8+6-4-12=-2, so invalid?

but there is no resistances, and V=iR? The voltage outside the path do not equate to 0, so is the circuit invalid?

Thank you!

Thank you. So is the equation that i got correct? Is vo also equal to 2io/12?

Yes i am sure, the one in color is the one that i have on my book. I already spent 3 4 hours on that problem because i can't get those answers so i am sure that's the one haha

Oh sorry, the first problem from the top is the correct one. The one in color
