Capacitor Discharge

Along with radioactive decay, this is a classic practical for taking natural logarithms in order to produce a straight line graph.
Often done in year 13, the basics of reducing uncertainties can be taken for granted and students can instead focus on using spreadsheets to process data and / or use data logging equipment for timing.
Students with electronics experience may wish to use 'bread boards' but leads and croc clips work just as well. Stabilised DC supplies or batteries produce better results than standard lab packs.
