Derive the equations below by using the given circuits:

R₁ R₂ R₂ R₂ 2 R₂ a) Resistance measurement + Vs R₂R₂ R₂ R R₂ Resistor box + out Potentiometer Rx b) Strain gauge measurement + Vs R vi R₂ + Vou Figure 6: Resistive Wheatstone bridge If the output voltage, Vo = 0, the bridge is said to be in balance. You can verify that when the bridge is balanced, out out Strain gauge Rx The resistive bridge can be used to measure the value of an unknown resistor (e.g. R ) by fixing the values of resistors R, and R, and then adjusting resistor R, using a “decade box" found in the laboratory until the bridge is in balance. Then, (6a) (6b)
