![Problem 4 (S.
A camera flash circuit is shown below. The flash bulb resistance is R; = 0.52, and the
battery voltage is V, = 9V. The flash bulb requires above 400mJ of energy to produce
a reasonable flash. Also, the flash circuit should be ready for reuse after 5s. Find the
required values of C and R, to satisfy both of these requirements.
