Hello everyone,

I am a first year student taking electrical engineering and am looking for a systematic approach to doing these problems.

If you guys (or gals) can offer any hints or tips to help me understand what this is, that would be great. Thanks

What is the book recommended for the class?

What kinds of problems are you talking about?
The book is introductory circuit analysis by Boylstead, 13th ed.

An example question:
Slide titled Controlled Sources Examples showing an inverting op-amp amplifier with Rin = 10kΩ and Rf = 120kΩ, derivation via KCL and Ohm's law, ending with Vout = -(Rf/Rin)·Vin = -12V.
 
You want a systematic approach to opamp problems? It's pretty much shown in the example you posted. What assumptions can you make about ideal opamps? How can you use those assumptions and KCL equations to solve for the transfer function of opamp circuits? :smile:
