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 an 850-µF capacitor is 280 V.

(a) Determine the energy that is used to produce the flash in this unit.

(b) Assuming that the flash lasts for 3.9 × 10-3s, find the effective power or "wattage" of the flash.
