Challenge: Camera flash

“

- It's time for another challenge problem. This time you'll be designing the circuit for a camera flash. Cameras rely on the ability of capacitors to quickly discharge, providing that short burst of high energy that powers the flash bulb. The battery in this camera can't directly provide energy fast enough to produce the voltage and current necessary to power the flashbulb. So, instead, the battery is used to solely charge a capacitor, and then when I take a picture, (camera clicking) that capacitor rapidly releases its stored energy to make a flash. The capacitors used in cameras operate at dangerously high voltages, and you should never take apart a camera flash because there's a real danger of getting shocked. So, for the sake of safety in this challenge, I've created this circuit which mimics the behavior of a camera flash, but at much lower and safer voltages. When the two way switch in the circuit is…
