Nettetfancy set of equations for that. The resistors R2, R3, and R4 have no effect when the output is grounded, and only the + input voltage is active. When you move the -input upward, the gain to the grounded output node is – R4/R3 x 1/R2. Since the ratio of the resistors is defined to be R1/R2 = R3/R4, then that gain is also equal to -1/R1. That ... NettetIt has been suggested that this article or section be merged into Frictional pressure drop.
