WebJan 27, 2024 · Youtube has several educational videos known as Ruhmkorff coils, but it seems that they are discontinuous sources. Not sure if discontinuous sources were useful for cathode ray experiments or measuring e/m ratio. Is anyone aware of the names of such devices which powered cathode ray tubes used by early physicists? Thanks.
