Because your charging source for this experiment may limit the number of electrons flowing into the Leyden jar, the smaller capacitor may actually charge to a higher voltage, while the larger capacitor will store more energy (probably or possibly at a lower voltage). It may be at exactly the same voltage, but many more electrons will be involved in the larger capacitor. So the problem is, what do you mean by your question "which (larger or smaller Leyden jars) can hold more static electricity"? If you have two capacitors, same insulator thickness, but different surface areas of the electrodes, the larger capacitor can store more energy at the same voltage. The other is the amount of energy stored which is a function of the number of electrons stored and the voltage potential that is observed. Voltage is only one attribute of the energy stored. In dry air, this voltage can be estimated as about 3,000 volts/mm. This is determined by measuring the distance that the spark initially jumps as the two electrodes are brought into close proximity. The measurement shown in the Science Buddies experiment measures the potential, or voltage, stored on the capacitor (Leyden jar). There are some definitions that have to be considered. The Leyden jar was charged by some source that provided a high voltage charge. There is an attraction between the two that creates an electric field, but because the insulator efficiently prevents the flow of electrons, the charge can remain stored on the capacitor for a period of time. One of the conductors having a positive charge, the other, a negative charge. The capacitor is capable of storing a quantity of energy. Think of a simple capacitor as two parallel metal conductors separated by an insulating spacer, or dielectric. Sciencejeff - The confusion seems to be "what is more static electricity"? A Leyden jar is fundamentally a capacitor.
