The circuit shown in Fig. 19–84 uses a neon-filled tube as in Fig. 19–23a. This neon lamp has a threshold voltage V, for conduction, because no current flows until the neon gas in the tube is ionized by a sufficiently strong electric field. Once the threshold voltage is exceeded, the lamp has negligible resis- tance. The capacitor stores electrical energy, which can be released to flash the lamp.
