Electric Arcs: Experiments Upon Arcs Between Different Electrodes in Various Environments and Their Explanation (Classic Reprint)

Excerpt from Electric Arcs Experiments Upon Arcs Between, Different Electrodes in Various, Environments and Their ExplanationIt is much easier to distinguish between the arc and the continuous discharge in a vacuum tube where the current is small and the large, such as that shown in a Geissler or Crookes tube, which has also been called by some a spark. The current in this case is much smaller than with the arc, and the potential difference is very much higher. Moreover with the arc the potential differ ence between the cathode, as the negative terminal is called, and the layer of gas in its immediate neighborhood is small, while with the glow discharge it is large. With the former it may be as low as 5 or 6 volts, while with the latter it must be as high as 300 volts.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
