calculate value for resistor in
I have an LMC6001 op-amp, and I would like to build the ph probe amplifier featured in the datasheet. Unfortunately, I am not sure what R9 is or should be. Does R9 control slew rate? How would I...

Inverting Op-Amp Circuit Problem
I am trying solve the question shown in the picture below (I am assuming the switch is down in the picture, I can't tell) The equation that I am using is Vout/Vin = - Rf/Rin because there is negative...

See this circuit: Applying KVL around the gate-source-GND-gate loop, I get Id = (Vg - Vgs)/Rs. I know the typical argument begins with, if Id increases then Vs increases, but I am not sure of how it...
