E.1.4 Wimshurst Static Machine

The Wimshurst Static Machine generates large sparks for entertainment or for use in various electrostatic experiments. The associated Leyden jars can be connected in or out of the circuit to illustrate the function of a capacitor -- in circuit, the sparks are much fatter and louder (Q larger), but of the same length (same maximum V), and much less frequent (longer time to build up the large Q).
