AC Arc

Plasma created by a power supply or function generator of alternating polarity. Typically, an arc excited at twice the frequency of the electrical grid (50 Hz except North America, which is 60 Hz). While not continuous, the period of low current as the polarity of the driving voltage commutes (switches sign) is brief compared to the overall experiment time.
