Determine the amount of energy stored in the capacitor that you used in the experiment when it is fully charged. Describe how that energy is put into the capacitor and how it is discharged from it. (i.e. describe energy flow, source and where does it go) Also determine the size of the plates and their spacing if your capacitor was an ‘air’ capacitor (i.e. only air between the plate).
