Unit 1: [10 marks: Natural Science] Table 1: Measurement Error Example An 820-ohm resistance with an accuracy of plus/minus 10 % carries a current of 10 mA. The current was measured by an analog ammeter on a 25-mA range with an accuracy of plus/minus 2 % of full scale. From Table 1, determine the absolute error in R (plus/minus) (ohms): 2 From Table 1, determine the absolute error in I of the full-scale range (plus/minus) (UA): 2 From Table 1, determine the relative error in measured I (plus/minus) (percentage): 2 Table 2: Measurement Systems Example v = 8 sin (150t + n/2 From Table 2. determine the crest factor (dimensionless): 2 From Error! Reference source not found.determine the time at which the point corresponding to zero degrees of the sine wave occurs (ms): 2 [10]
