$10\mathrm{.}18.$ A bridge circuit is used to measure the output of a strain gage having a resistance of $110$ under zero conditions. $R_2=R_3=100,$ and the galvanometer resistance is $75.$ The gage factor is $2\mathrm{.}0.$ Calculate the galvanometer current when $lon=300\frac{m}{m}$ for a power voltage of $6\mathrm{.}0$ V $.$ Also, calculate the voltage output of the bridge for a very high$-$impedance detector.
