Extracted text: 2021/E Q1/ Write SI base units with their symbols (five only), and then mention also five SI coherent drive units (with special names and expression in terms of SI base units). Q2/ 1- Is there similarity between Errors and Uncertainty? State this. 2- As a part of what? The measurement carı be making. Q3/ Two resistors R, and R, are connected in series. Let R, = 10 2 ± 0.52 and R2 = 10 2 ± 0.52. Find the maximum and expected values for the uncertainty in the combination. Q4/ answer the following True or False questions(answer 10 only) 1- Systematic errors can be eliminated by recalibrating the equipment 2- Gross (human) errors can be treated mathematically 3- Accuracy of a measurement is an indication of how close the reading is to the average value 4- The smallest incremental quantity that can be measured is the resolution 5- The precision is an indicator of consistency in a set of measurements 6- comparing two pieces of string to see which is longer is a measurement 7- A study of errors is a first step in finding ways to reduce them 8- The uncertainty may be caused by individual inaccuracy of sensors 9- Transducer is defined as a device which converts a physical quantity into an electrical quantity 10- Sensor is act as secondary element of transducer 11- May A/D converter is act as variable conversion element
