Q2. Answer the following questions, using your own words and by showing full details and steps of the solution. (5 Marks) a) The voltage across a resistor of a circuit is measured 10 times by Digital Multi-Meter and the following measurements are obtained (units of Volts): 4.293, 4.295, 4.297, 4.293, 4.292,4.290, 4.312, 4.321, 4.521, and 5.000. (3 Marks) If the theoretical (actual) voltage of that resistor is 4.296 V, which can be taken as the correct value for the voltage of that resistor. Describe the Digital Multimeter in terms of its precision and accuracy and explain your answer. b) An instrument is calibrated in an environment at a temperature of 20 C and the following output readings y are obtained for various input values of x: (2 Marks) 26,2 13.1 5 10 39.3 15 52.4 20 65.5 78.6 25 30 When the instrument is subsequently used in an environment at a temperature of 50 C, the input/output characteristics change to the following: 29.4 14.7 5 44.1 15 58.8 73.5 88.2 25 30 10 20 Determine the sensitivity drift caused by the change in temperature.
