R1=1kΩ, R2=10kΩ, R3=910Ω
Determine the effect on the output if the circuit shown has the following fault (one fault at a time)
a. Output pin is shorted to the inverting input.
b. R3 is open.
c. R3 is 10kΩ instead of 910Ω.
d. R1 and R2 are swapped.
I have no idea what the answer to "a" is. I believe the answer to "b" is the output signal would be in saturation. I believe the answer to "c" is there would be no change. Finally I believe the answer to "d" is the closed loop gain would decrease significantly. Please let me know if any of my answers are correct and what the solution to "a" might be. Any help with this would be greatly appreciated. Thank You
P.S. Here is a link to a schematic similar to the one in my book http://www.elecircuit.com/opamplifiers/The-Inverting-Amplifier-1210.html
