P5-Consider a standard strain-gage bridge with R, as the only active gage and R3-R4. Obtain an expression for R, in terms of R2. vo, and vref. Show that when R1-R2. we get v 0 -a balanced bridge- as required. Note that the equation for R. assuming that vo is measured using a high-impedance voltmeter, can be used to detect large resistance changes in R1. Now suppose that the active gage R1 is connected to the bridge using a long, twisted...
