Please check attached image.
I am doing some op amp practice problems and I came across this problem:
I have to find the potential at the inverting input of the simple circuit model of the op amp. The op amp would be a basic inverting amplifier. I have to give the answers using A, Vi, Ri, Rf, Rd, Ro. There are no loads.
I am familiar with how to work with an inverting amplifier similar to here: http://www.electronics-tutorials.ws/opamp/opamp_2.html
However, how do I work with the attached image?
Kirchoffs's Law and Ohm's Law
The Attempt at a Solution
Have it done by hand, but pretty much this: http://www.electronics-tutorials.ws/opamp/opamp_2.html
