Coursework 2: Discharge of a Capacitor through a Resistor
Your research investigation is to investigate the discharge of a capacitor through a resistor. You will investigate the factors that affect the discharge time and graphically find the time constant of the capacitor resistor combination. Compare your experimental value of time constant with the calculated one. Discuss uncertainties and errors. You will produce a formal laboratory report using a word processor (Microsoft Word). It should contain 1500 – 2000 words, plus calculations, diagrams, references etc. The final report should contain the following sections: Introduction Theory Procedure Results Analysis Discussion Conclusion References The maximum number of marks for Coursework 2 is 90. The following marks are given for each section:
Final Report (100%) The Final Report is marked out of 90 and is worth 100% of the overall mark for Coursework 2 Introduction and Theory (10 marks) The title and aim of the experiment should be clearly described. Theory should be introduced and at least 3 references cited correctly. The Introduction and Theory should be separate Procedure (15 marks) The equipment used should be listed. Diagrams should be labelled and clear. The procedure should be clearly explained in the student’s own words.
Results (15 marks) Observations, including repeat observations where appropriate, should be recorded. Show realistic uncertainty values. Correct units should be given for all physical quantities. Measurements should be taken over an appropriate range. Analysis (30 marks) The data should be processed to obtain a straight-line graph, where possible. Graphs should be correctly titled with sensible scales and axes. Points should be plotted accurately. A best fit line should be drawn. The gradient should be determined correctly using least squares fit. The gradient and intercept should be used appropriately. Data should be processed and displayed appropriately. Relevant physics principles should be discussed. Calculations should be carried out correctly and checked for accuracy. Uncertainties in calculated values should be determined correctly. Discussion (10 marks) Valid conclusions should be clearly stated. Realistic modifications should be suggested to improve the experiment. Style (10 marks) The report should be appropriately structured with subheadings. The report should not contain grammar or spelling errors. A good academic style of writing should be used. References should be cited and a reference list in Harvard style should be provided. The submission deadline is 5pm on Thursday 11th March 2020 and must be submitted to
the NCUK Itslearning website. Do proofread your report and ensure you submit the right
file as only one submission is allowed.
