## Homework Statement

For the following circuit, if Rth = 50kΩ, Ri = 1TΩ, and Ro = 50Ω, calculate the output voltage. Do not neglect Rth, Ri, or Ro.

Circuit is here.

## Homework Equations

Possibly KCL and/or KVL, possibly the non-inverting op-amp equation Vo=(1=Rf/Rs)Vi, Ohm's Law V=iR.

## The Attempt at a Solution

This is the first OpAmp problem I've done, and I'm really not even too sure how to start it, and my notes haven't been of much help. All I've done so far is solve for the current through Rth using the 2.3V source and Ohm's Law, but I'm not sure that's even relevant. It also looks to me like the current would be the same through Ri since it looks like they're in series, but that sounds wrong to me, for whatever reason. I would greatly appreciate if someone could walk me through how to do this.
