The experiments of Millikan and Ioffe
The movie tells about the experiments that independently from each other, held A. Ioffe and R. Milliken. These experiments proved the existence of electrons and demonstrated how it is possible to observe individual electrons. The film shows the schematic of the experimental units, and the nature of the motion of a charged particle in an electric field. An explanation is given to the discrete nature of the particle charge with a corresponding change of the charge plates and the electric field.
