In the center, an electrode is powered by a small circuit that produces a high-frequency, high-voltage alternating current. This electric field strips electrons from the gas atoms: the gas becomes a \u003cstrong\u003eplasma\u003c\/strong\u003e, the fourth state of matter, and emits light as it de-excites.
