electrophorus, device used to generate static electric charges. It has two parts: a nonconducting plate (e.g., of hard rubber) that is negatively charged and a metal plate with an insulated handle. A positive charge is induced on the metal plate by placing it on the charged plate and then grounding the metal plate momentarily. This positive charge can then be used for experimentation. See electrostatics electrostatics, study of phenomena associated with charged bodies at rest (see charge ; electricity ).
