Electric discharge is a phenomenon that occurs when a large amount of electric charge flows through a medium, causing it to ionize and produce light or heat. There are various synonyms to describe this event, such as electrical spark, lightning bolt, plasma discharge, arc flash, and electric arc. Each of these terms is used to describe different kinds of electric discharges that occur under different circumstances. For instance, an arc flash is a sudden and intense electric discharge that occurs in an electric circuit due to a short circuit or an equipment failure. Similarly, a plasma discharge is a type of electric discharge that occurs when ionized particles interact with a magnetic field. Overall, the synonyms of electric discharge provide a way to describe the different manifestations of electrical energy and its impact on the environment.
