Lets say we are given a non-inverting Op-Amp
The gain of this circuit would be A = 1 + (R1+R2)/R3 if the switch is off.
What happens when the switch is turned on? It shorts the R1 and R2 resistors am I correct? Does this mean that R1 and R2 will behave as if they are in parallel, and decrease the overall gain of this amplifier?
Appreciate your help!
