Do I need a large-value capacitor to do this experiment?
To do this experiment, you will need the following: Large-value capacitors are required for this experiment to produce time constants slow enough to track with a voltmeter and stopwatch. CAUTION: Be warned that most large capacitors are of the electrolytic type, and they are polarity sensitive!
How is capacitance determined in a capacitor?
For a capacitors are electronic the capacitance depends on the physical and geometrical proprieties of the device. It is given operationally by the ratio of the charge Q stored in the device and the voltage difference across the device ΔV. The schematic symbol of a capacitor is two parallel lines which represent the capacitor plates.
How do you find the average discharge time of a capacitor?
Capacitors in parallel follow the relationship: Therefore, for two capacitors you should find the average discharge time is the sum of the two individual discharge times. In addition, for the three of them, it should be the sum of all three.

How do you calculate the capacitance of a demonstration capacitor?
But you can calculate this capacitance. If the plates are not too far apart, the demonstration capacitor can be correctly modeled as a parallel plate capacitor, which obeys the equation: C = (εoA)/d Use this equation to calculate the capacitance of the demonstration capacitor. Show your work on the worksheet.

8.2: Capacitors and Capacitance
Notice from this equation that capacitance is a function only of the geometry and what material fills the space between the plates (in this case, vacuum) of this capacitor. In fact, this is true not only for a parallel-plate capacitor, but for all capacitors: The capacitance is independent of (Q) or (V). If the charge changes, the potential changes correspondingly so …
Discharging a Capacitor
Carol uses a multimeter as a voltmeter and a stopclock to do the timing manually. She suggests measuring V every ten seconds: it''s hard to record it any more frequently, but take less frequent measurements and the graph will be hard to draw, with too few data points. Any voltmeter will do: digital, analogue, multimeter, or even an oscilloscope.
