Q4//For the dc circuit shown in Fig.(3). One voltmeter and one wattmeter

Q4//For the dc circuit shown in Fig.(3). One voltmeter and one wattmeter are installed on the circuit to measure the following quantities: Z1 for the measurement of the power consumed by the load. Zz for the measurement of the voltage at bus 2. The meter readings are: Z1=P=15.8 W; zz= V2=7.9 V The variances of the measurements errors are: o,= (0.01)? ; oz= (0.02)2 Determine the weighted least-squares estimates of the voltage at bus 2? Perfe m o: teration. %3D %3D 12 2 Z1 Pm A Z2 10 V Load 16 w Fig. (3)
