Consider the simple potentiometer circuit shown in Figure 6.9 with reference to Figure 6.8. Perform a design-stage uncertainty analysis to determine the minimum uncertainty in measuring a voltage. The following information is available concerning the circuit (assume 95% confidence): E = 10+ 0.1 V R = 10019 R = 10092 Rg Rx = reading 2% + where Rg is the internal resistance of a galvanome- ter. The null condition of the galvanometer may be assumed to have negligible error. The uncertainty associated with R is associated with the reading obtained from the location of the sliding contact. Estimate the uncertainty in the measured value of voltage at nominal values of 2 and 8 V.
