ntact with the glass,further pressure does not increase the electrification. The surfaceof the rubber should be covered with a conductor such as that 72] FRICTIONAL MACHINE 107 variety of sulphide of tin known as aurum musivum, or, still better,with Kienmai/ers amalgam., which is composed of zinc,… … Fig. 54. difference ot potentials between them, the glass becoming positivelyelectrified, and the rubber negative. This difference of potentialsis at first vei-y small, since the equal oppositely electiified suifacesare very close together. But as each portion of the glass movesaway from the…
