The term "peak arc current" is commonly used in the field of electrical engineering to refer to the highest amount of current that is flowing through an electrical circuit at any given time during the arc discharge process. Some common synonyms for "peak arc current" include maximum arc current, highest arc current, and peak discharge current. Other words that can be used to describe this phenomenon include peak plasma current, arc voltage, arc energy, and arc duration. Understanding the various synonyms for "peak arc current" can help engineers and technicians better communicate about the behavior of electrical circuits and the performance of electronic devices.
