Learning Goal: I’m working on a electrical engineering question and need guidance to help me learn.
I have to design a wheatstone bridge that has voltagefollowers and a differential amplifier that has an adjustable output range of-10 to 10 volts. I have the variable resistors R1 and R4 adjustable torepresent a 350 ohm strain gauge.Without the voltage followers, I can get from zero to ten volts. When I connect voltage follower 1 and 2 thecircuit stops working. Here is thecircuit I am trying to get working. Whatcan I do to get it to work? The op amps are 741.
