Write A Conclusion For The Lab With The Following Format A One Paragr

Write a conclusion for the lab with the following format: a one paragraph (5-10 sentences) typed summary of the results of your experiment. It will consist of answering the following four elements, using complete sentences and proper grammar: • What was the purpose of the lab? To measure a quantity, verify a theory, etc.? There may be more than one purpose to an experiment. • Discuss quantitatively the main result of the lab. Was the quantity measured accurately and/or precisely? Was the theory proved or disproved? Cite specific values, from the results, to numerically justify your answers to these questions. • Identify at least one source of error in the experiment. Qualitatively describe how this error affected or might affect the raw data and the final results. Do not use “human error” as your source of error. • What improvement or change would you make for this experiment to increase its accuracy and/or precision?

The primary purpose of this laboratory experiment was to measure the electric resistance of a given material and verify the theoretical relationship between resistance, length, and cross-sectional area. The experiment aimed to determine whether the measured values aligned with the established formula \( R = \rho \frac{L}{A} \), where \( R \) is resistance, \( \rho \) is resistivity, \( L \) is length, and \( A \) is cross-sectional area. The main result indicated that the measured resistance values increased linearly with the length of the material, confirming the proportional relationship predicted by the theory. Specifically, when the length of the wire was doubled from 0.5 m to 1.0 m, the resistance increased from 2.3 Ω to 4.6 Ω, showing excellent agreement with theoretical expectations and demonstrating accurate and precise measurement. However, minor deviations occurred due to temperature fluctuations, which affected the resistivity of the material, slightly increasing resistance values beyond the theoretical predictions. These fluctuations may have introduced a small systematic error, impacting the fine accuracy of the measurements. To improve the experiment's accuracy, implementing temperature control or conducting measurements in a temperature-regulated environment would reduce thermal effects, leading to more consistent and reliable resistance readings. Overall, the experiment successfully verified the proportionality between resistance and length, with results supporting the theoretical model within acceptable experimental uncertainty.
