Through animated drawings and photography explains the hypothesis that electricity consists of unit elementary charges. Demonstrates the conduction of electricity through solutions, gases, and vacuum: Faraday’s laws; movement of charges in vacuum tubes: operation of photoelectric cells: and reproduction of sound on film. For high school and college groups. We digitized and uploaded this film […]

Shows the nature of repulsive and attractive forces between bodies charged by contact under different conditions. Demonstrates techniques of charging by induction, and the part played by conductors and insulators, and compares the use of two measuring devices, the electroscope and the electrometer. Depicts the development of atmospheric conditions leading to the discharge of lightning […]
