The circuit below is composed of a Wheatstone bridge and amplifier. A Wheatstone bridge is a type of circuit commonly used to convert resistance changes into voltage changes; the most common device used with a Wheatstone bridge is a strain gauge. A strain gauge is a sensor that converts strain (changes in length) to a change in resistance. Essentially a strain gauge is just a wire being stretched (recall a resistor's resistance depends on length; if you stretch it, its resistance will change!). The resistance change of a strain gauge is very small (order of milli-ohms), and as such, the voltage difference between the two arms of the bridge is typically amplified Your task is to determine the amplifier's gain, b, that will result in a relationship between output voltage and change in resistance such that, Vo-5 volt.
