The lab report must include the following: • Title • Introduction • Experimental Details or Theoretical Analysis • Results • Discussion • Conclusions and Summary • References.
Lab Activity Please follow the steps given below to conduct the experiment: • This lab requires you to produce a lab report to determine “The Stored Energy and Stored Charge.” This is the “Title” of your lab report. • Read the relevant chapter on capacitance and add an “Introduction.” You conduct this lab by connecting to the PhET website by clicking on the link given below (or where applicable through the embedded simulation on the lab page).
• Once you open the simulation, select “Capacitance.” Then, please check all the boxes on the simulation page. Follow the lab scenarios to change the voltage, plate area, and separation. Remember to note the experimental values that appear on the simulation ( You will compare these values with theoretical calculations later.) All movements and tools you use in this simulated experiment will form the “Experimental Details” section of the lab report. You must keep a record of all the values appearing on the screen as experimental values for the scenario. These values also form part of the “Results” section of the lab report. Now, complete the theoretical calculations. These calculated values also form the “Results” section of the lab report. • Now, you can complete the “Discussion” section of your lab report by comparing the values and discussing any differences in the theoretical and experimental values and any other information relevant to the experiment. • Complete the lab report by adding a summary to the “Conclusion” section of your lab report. • Submit the lab report to the relevant Canvas Dropbox .
Lab Scenario
Note the experimental values for “Top Plate Charge” and “Stored Energy” for each of the following scenarios. You will then calculate the same values theoretically for each of the above scenarios using relevant equations and compare them to experimental values. 1. Capacitor separation 2mm, Capacitor plate area 100 m2 . 2. Capacitor separation 2mm, Capacitor plate area 200 m2 . 3. Capacitor separation 2mm, Capacitor plate area 400 m2 . 4. Capacitor separation 4mm, Capacitor plate area 100 m2 . 5. Capacitor separation 4mm, Capacitor plate area 200 m2 . 6. Capacitor separation 4mm, Capacitor plate area 400 m2
