Investigation on the factors that affect the storage capacity of Leyden Jars.
Yeo Jun Yang, Marco Obe, Siao Boon Kiat, Gabriel Leong

A Leyden Jar is the original form of the capacitor, made to store static electricity. A normal design usually is made of a glass jar with conducting metal foil on the inside and outside of the jar. A rod electrode protrudes out of the jar and is connected to the metal foil so as to allow the Leyden Jar to be charged. To test the effectiveness of homemade Leyden Jars, we attach a Leyden Jar to a Van de Graaff Generator and allow it to charge, then measure the amount of short circuit voltage in the jar with a multimeter.
