The circuit shown in Fig. 19–84 uses a neon-filled tube as inFig. 19–23a. This neon lamp has a threshold voltage V, forconduction, because no current flows until the neon gas in thetube is ionized by a sufficiently strong electric field. Once thethreshold voltage is exceeded, the lamp has negligible resis-tance. The capacitor stores electrical energy, which can bereleased to flash the lamp. Assume that C = 0.150 µF,R = 2.35 × 10° N, V, = 90.0 V, and E = 105 V. (a) Assum-ing the circuit is hooked up to the emf at time t = 0, at whattime will the light first flash? (b) If the value of R is increased,will the time you found in part (a) increase or decrease?(c) The flashing of the lamp is very brief. Why? (d) Explainwhat happens after the lampRflashes for the first time.wwNeonE = 105 VFIGURE 19-84lampProblem 86.
