The electronic flash attachment for a camera contains a capacitor for storing the energy used to produce the flash. In one such unit, the potential difference between the plates of a 765 µF capacitor is 345 V.
(a) Determine the energy that is used to produce the flash in this unit.
Using the formula:
Energy = .5C(V^2) i found the energy to be 45.527 J
(b) Assuming that the flash lasts for 5.0 10-3 s, find the effective power or "wattage" of the flash.
I can not find a formula to convert the given information into wattage however.
