Thanks for the explanation. I think I understand it better now, even though I still can't get the correct answer. The attachment is a quick sketch of a section of the circuit with my variables labelled. Here's my KCL equations: 1) Vg/4000 = -Vx/20000 so Vx = -5Vg 2) Vx/(aR) =...

Homework Statement The op-amp in the circuit shown is ideal (please see attachment). The adjustable resistor RΔ has a maximum value of 160 kΩ and α is restricted to the range of 0.22 ≤ α ≤ 0.7. (a) Calculate the range of vo if vg = 40 mV (b) If α is not restricted, at what value of α...
