TIONS AND ELECTRIC WAVES. 261 electrical stress. The explanation here given of the entire reliefof the electrical stress between two plates by the establishmentof a conducting line (line of slip) between them applies to twoadjacent oppositely charged bodies of any shape. An electricspark is a line… … Fig. 204. The Hertz oscillator.—Let A and B, Fig. 204, be two metalballs connected to two short rods between which is an air gap(spark gap). Imagine charge to have been collecting on A andB, positive charge on A, negative charge on B, until a sparkjumps across the air gap, thus establishing a…
