7- A simple relaxation oscillator circuit is shown in the figure below. The neon lamp fires when its voltage reaches 75 V and turns off when its voltage drops to 30 V. Its resistance is 100 Ohms 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?
