Capacitor Discharge through a Resistor - Analysis of the Experiment

This is the analysis of data for the experiment to determine an unknown capacitance. A capacitor discharges through a resistor (known resistance) and the potential difference across the capacitor is measured along with time. Two methods are used to determine C:
① Taking logs and using gradient from lnV v. t graph.
② Using time constant which is found by analysing V v. t graph.
There is a worksheet to go with this experiment so you can try the analysis yourself: www.tes.com/teaching-resource... is a spreadsheet available to help analysis of the data from this experiment:www.tes.com/teaching-resource...
Relevant concepts: capacitance, potential difference, natural logs, time constant.
Experiments with capacitors, like this one, are mandatory practicals for many physics specifications. So this is good practice for OCR physics A, AQA A-Level physics, Edexcel A-Level physics, CPAC, PAG, practical endorsement.
