I'm a first year student doing elec eng. and I'm wondering about the direction of current in an op amp (Where the current flows from to where it is going). I'm wondering this so I can use KCL to find an expression for Vout, but I usually end up getting the directions wrong.
This is an example of the type of amp I'm asked to detail about in my exams. Is there a rule about the way the current flows depending of the feed back etc?
Thank you for your help!
