Solving for the voltage gain of an inverting op amp
Find the gain for an inverting op amp.
3. The Attempt at a Solution
I tried to solve for the gain but I ended up getting a positive gain. I think I made a mistake with the current directions but I always thought that when doing nodal analysis, it doesn't matter what direction your current arrows are? Since the math should always work out? I am not too sure... What am I doing wrong?
