Insulated elongated ellipsoid.
notes: label: Description (Brief)
content: Conducting Elongated Ellipsoid, brass on glass rod with a wooden base. To show the difference in distribution of charge on pointed and blunt surfaces. The concentrated charge on the pointed end will attract a spark from a longer distance than will the diffuse charge on the blunt end. This relates to 18th century debates about the preference for pointed or blunt tips on lightning rods. Originally from Woodstock College. Ref: Ganot 4th ed. p. 620. Tag on bottom, "P. D. W. C./ El10".
