1. The problem statement, all variables and given/known data FIGURE 2 shows an op-amp circuit with a constant input voltage V connected to the inverting input. If the output voltage is +2.4 V, calculate the value of V. Schmitt trigger values: R1=4.8 ohms R2=2 ohms V OUT= +2.4V 2. Relevant equations V+=(R1*V SAT)/(R1+R2) 3. The attempt at a solution V+=11.52/6.8=1.69V Now this is the Reference Voltage going to the non inverting terminal but I'm lost as to where to go from here, this would indicate that V is less than 1.69? Any help to point me in the right direction would be much appreciated. This is the first time I've studied the electronics side of things and it's safe to say I'm struggling a little.
