Measurement and Uncertainty Analysis
During the workshop, practical exercises were conducted to utilize a multimeter for measuring various electrical components, such as batteries, solar cells, resistors, and power outlets. The primary aim was to comprehend the process of obtaining accurate measurements and evaluating the uncertainties linked with these measurements.
The workshop commenced with an introductory session on the principles of electrical measurement and the operational functions of a multimeter. Subsequently, participants were guided through a series of hands-on experiments where they practically applied the acquired concepts.
Each experimental setup included the utilization of a UNIT-T UT 133B multimeter, with instructions to measure the voltage, current, and resistance across different components, including batteries, solar cells, and resistors. Additionally, measurements were taken from power outlets to discern the mains voltage.
Throughout the experiments, significant emphasis was laid on adhering to proper measurement techniques, encompassing the selection of the appropriate range on the multimeter, ensuring accurate connections, and minimizing potential sources of error.
Following the data collection phase, an analysis of the measurements was conducted to identify the uncertainties associated with each reading. Factors such as instrument precision, environmental conditions, and measurement techniques were taken into account during this analysis.
Finally, the collected measurements and their respective uncertainties were compiled. This compilation served as a comprehensive record of the experimental data, facilitating further analysis and discussions on the outcomes obtained.
