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...
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...

Hi, I attached a pdf file with the problem. My question is, for the lower right...
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?
