Hi, How to calculate the output voltage of the circuit is shown below. Using the superposition principle is the best or the one that you recommend. I'm using strain gauges based on the Wheatstone bridge, which brings me here. I calculated Thevenin resistive load and voltage source(302ohm, 0.7v). If I had Wheatstone bridge resistor values R1, R2, R3, R4, 350ohm, 350, 350, and 200, what is the voltage across a voltmeter?
