(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A. solve for input equiv. resistance =Vtest/Itest as a function of R1,R2, and R3

B. Calculate Req for R1 = R2 = 2.2K(ohm) and R3= 4.7k(ohm)

2. Relevant equations

Va = Vc = Vtest

3. The attempt at a solution

I have no idea how to approach this, I think it would be most helpful to be given the final Itest and Vtest values in terms of R's so that I can make sense of it, because my teacher tried getting me to do KCL and KVL and it pretty much failed and I got 1/1
