A simple relaxation oscillator circuit is shown in Fig. 7.145. The neon lamp fires when its voltage reaches 75 V and turns off when its voltage drops to 30 V. Its resistance is 120 Ω when on and infinitely high when off.
(a) For how long is the lamp on each time the capacitor discharges?
(b) What is the time interval between light flashes?
