Consider the entire resistors in the bridge circuit are equal. The resistance and change in resistance are given as 3kΩ and 30kΩ. Calculate the output voltage of differential instrumentation amplifier? Correct Answer 1.65v

The output voltage of the circuit is Vo =-(RF/R1)×(△R/R)×Vdc = (5.5kΩ/100Ω)×(30kΩ/3kΩ)×3 = 1.65v.
