Johnson's shot noise experiment had the same goal as this experiment, which used X-rays to ionize a gap that contained air as a dielectric.
Johnson's shot noise experiment had the same goal as this experiment, which used X-rays to ionize a gap that contained air as a dielectric. This experiment used three spacer balls to separate the plates of its capacitor, which usually reached a potential of about three thousand volts. The fundamental technique of this experiment was to balance the force of gravity with the forces of buoyancy and viscosity, but its result was off by about six percent due mostly to an incorrect value used for the viscosity of air. Name this 1909 experiment to measure the fundamental charge of an electron, conducted by Robert Millikan.
