The flash unit in a camera uses a special circuit to "step up$"$ the $3\mathrm{.}0$ VV from the batteries to $360$ VV $,$ which charges a capacitor. The capacitor is then discharged through a flashlamp. The discharge takes $11$ ss $,$ and the average power dissipated in the flashlamp is $1\mathrm{.}0105$ WW $.$

Part A

What is the capacitance of the capacitor?

Part A

A parallel$-$plate capacitor consists of two square plates $19$ cmcm on a side, spaced $0\mathrm{.}45$ mmmm apart with only air between them. What is the maximum energy that can be stored by the capacitor?
