An instrument is described in which the first appearance of corona is used as a measure of the applied voltage. Three methods for detecting the first appearance of corona have been developed, in addition to the method of visual observation. These methods involve the use of the electroscope, the galvanometer, and the telephone respectively.

Collecting Corona (Corona Sammeln)
The coronavirus pandemic has posed major challenges to the museum landscape. Not only because their presence was not perceivable for a long period of time, but also because their social significance was re-located.
