As seen in the circuit diagram picture below, the Pearson-Anson relaxation circuit is often used to blink neon lamps. According to what I have read, the lamp does not permit a current until the capacitor reaches the voltage threshold, causing the gases in the lamp to ionize and a sudden current. Once the capacitor discharges enough, the voltage falls below the lower threshold, the current drops to zero, and the power source begins charging the capacitor again to repeat the process.
My question is, why doesn't the battery just turn on the lamp and keep it lit while charging the capacitor. The voltage of the capacitor will never exceed the battery so the battery must have enough voltage to turn the lamp on. Also, since the lamp is in parallel, isn't the voltage difference across the lamp the same as that of the capacitor? I don't see why the battery wouldn't just light the lamp right away. Can anyone clarify this for me? Thanks in advance.
