Eb-8 Freier & Anderson 5C30.10 Leyden jar Sparks from an electrostatic generator are intensified when a Leyden jar or aluminum plates are connected in parallel with spark gap. D&R, E-210 Dick and Rae 5C30.10 Leyden jars on Toepler-Holtz The Toepler-Holtz produces weak sparks without the Leyden jars and strong less frequent sparks with the jars connected.
