Heart-shaped electrode is used in a high voltage discharge recorded on film. Initially, the plastic builds up a charge on the surface and acts as a capacitor. At a certain potential voltage, the film, which is dielectric material, breaks down and allows electrons to flow. The flowing electrons superheat the air resulting in an electrical spark which is recorded in the film emulsion. These are often called Lichtenberg Figures, named for the German physicist Georg Christoph Lichtenberg, who originally discovered and studied them in 1777. | |
