1. The problem statement, all variables and given/known data Here's the network: R1=100 The gain ranges from -1V/V ---> -10V/V and the potentiometer R4=10. Is R4 and R3 in parallel with each other? I cant seem to get the right answer.... Moreover, this is what was done: -(R2/R1)(1+(R4/R2)+(R4/R3))=-10 Can someone please explain this. I know what the -10 means, I just do not really understand what was done here, whether it be a voltage divider, current divider or neither. Regards, D.
