(a) A d.c bridge based on strain gauge sensor is used to measure the vehicle weight. The values of Vae = 5 V, R1, R2, and R3 is 150 kN. The value of strain gauge, R4 before loaded is 150 k2. Before the measurement, a standard load with weight of 6000 kg is used for calibration. The galvanometer, 1, is flowed about 2.25 uA. Analyse the circuit to determine values of Rih, Vth and R4 when it is loaded. Assume the value Rm of galvanometer is zero.
