VI – 1 The data for V-1, V-2, and V-3 is shown below. DC Wheatstone bridge for resistors. R 3 = 300 Ω σRx is found using equation 11 in the manual Unknown Resistor L 1 (cm) L 2 (cm) σL(cm ) R x (Ω) σRx(Ω ) R m (Ω) A 61.5 38.5 .05 187.8 .29 143 B 52.8 47.2 .05 268.3 .38 210 C 38.4 61.6 .05 481.3 .73 380 D 17.5 82.5 .05 1413. 3 4.13 976 Resistor R m (Ω) ) R x ± σRx(Ω) In Range A 143 187.8 ± .29 No B 210 268.3 ± .38 No C 380 481.3 ± .73 No D 976 1413.3 ± 4.1 3 No The R m values are not in the range of R X ± σ RX , this could have happened because of certain human errors while taking the readings of L 1 and L 2 . Also, one of the reasons why error was more than expected if there was a systematic errors that is if the DMV reading was off by a few units . VI- 2 The data for V-4 is shown below. AC Wheatstone Bridge for resistors. R 3 = 300 Ω, f = 500 Hz σRx is found using equation 11 in the manual Unknown Resistor L 1 (cm) L 2 (cm) σL(cm ) R x (Ω)
