A bridge circuit is used to measure the output of a strain gage having a resistance
of 110 under zero conditions. R2 = R3 = 100 , and the galvanometer
resistance is 75 . The gage factor is 2.0. Calculate the galvanometer current
when = 300 μm/m for a power voltage of 6.0 V. Also, calculate the voltage
output of the bridge for a very high-impedance detector.
