Question

Problem 3 In the circuit shown at right, a flasher bulb is wired in parallel with the capacitor. When the voltage across the bulb (and the capacitor since they are in parallel) reaches 60 V charge will arc across the bulb making it flash and discharging the capacitor, at which point the capacitor begins to recharge starting from zero. R 1 M$\Omega$ C neon bulb V 100 V Figure 5. Flasher circuit. 1.). What value should the capacitor have if you want the bulb to flash every 10 seconds? 2.). If the power supply voltage were only 80 V and everything else in the circuit were the same, how long would it take between flashes? Problem 4. You have 8 resistors each with a value of 10 ohms. Draw a combination that uses all 8 resistors and has a total resistance of 42.5 ohms.

          Problem 3
In the circuit shown at right, a flasher bulb is
wired in parallel with the capacitor. When the
voltage across the bulb (and the capacitor since
they are in parallel) reaches 60 V charge will arc
across the bulb making it flash and discharging
the capacitor, at which point the capacitor begins
to recharge starting from zero.
