The book explains, in engineering rather than mathematical terms, the application of electrostatic principles for designing practical devices. Each chapter concentrates on a single electrostatic concept with applications to a particular device. Now in its third printing, the text is organized by the scale of electrostatic effect. Part One deals with the electrostatic fields in a uniform linear medium. Part Two introduces particles moving in the field. Part Three allows for a complex continuum. Part Four describes interactions between electrostatic devices and external circuits using terminal relations. In addition to providing a unified and comprehensive treatment of the fundamentals and applications of electrostatics, the author offers numerous examples, including copy machines, smoke detectors, high-speed printers, and the electrofusion of living cells. The epilogue provides more applications in various industries, plus bibliographies and review articles.
