1. * The purpose of the record of an experiment is to explain clearly and concisely what you are trying to do, what you actually did, what you actually observed, and what you concluded from your observations. PHYS3330: Lab Report *You lab report should be understood by someone who is not taking this courses. *Explain variables you introduce. Use the consistent symbols and variables throughout your lab reports including figures, tables and plots. *Your lab report must contain the followings: -Title -Objective -Idea/Apparatus/Theory -Procedure -Result and Data analysis -Conclusion

2. Lab Reports: Details of Contents and Examples Title: Title of the lab Objective/Goal: One or two Sentences of Basic intent of the experiment name, Partner name, section etc

3. Ideas/Theory/Apparatus: Describe the main ideas or equations that will be used in the lab. You can include the circuit diagram or schematics here.

4. Ideas/Apparatus: Describe the main ideas or key equations that will be used in the lab. You can include the circuit diagram or schematics here.

5. Procedure: Summary of process you followed while carrying out the experiment. no more than ½-1 pages. Voltage divider Wheatstone Bridge Copper wire resistivity measurement

6. Result and Data Analysis: -The complete data set : Uses of table is strongly recommended - Calculation of results: Detailed numerical sample of each type with unit and conversion. - Relevant Plots (including axis label, unit, title) - If you have not reached the desirable results, explain how you troubleshoot and the result. Voltage divider

7. Wheatstone Bridge When R x changed by 5% by adding 50 Ω, ΔR x = 50Ω, ΔV meausred = 0.184V ΔV_calc = 0.190 V. There was 3% discrepancy. when the bridged is “balanced” (ΔV =0) Result and Data Analysis ****Add PLOTS in this section if it is needed -Check axes labels, units and title. Fig.4 Bode plot for high Pass filter

8. Copper resistivity measurement Thus resistivity from DMM (ρ DMM ) and 4-terminal measurements (ρ 4tc ) is ρ DMM = 1.5 μΩ cm and ρ 4tc = 1.72 μΩ cm Each values has corresponding error coming from the reading of voltmeter. They are...... These values is compared to the known value from the pre-lab 1.69μΩ cm has ***% of error. Result and Data Analysis

9. Conclusion: -Summarize your results and compare them to accepted or calculated values. (if you did this in analysis section, say again in brief form!) -If you have suspicions and/or large discrepancy in your result, discuss here with reasonable quantitative estimates -You lose points by simply unsubstantiated or incorrect guess -Stick to scientific conclusions! Not opinions, no personal comments! (Bad example)... This lab was fun and I learned a lot. It is really sad that we did not get the right result in the end. kΩkΩ kΩkΩ
