Abstract

Yost examines the discharge from the electrodes of a DSI Wimshurst generator. Schlieren imaging reveals a coherent thread constantly emanating from charged, pointed negative electrodes, and cumulus puffs at the negative electrode upon discharge. Corona effects of different-shaped cathodes and anodes are observed in the dark under a microscope.
