I'm getting 4.4 because I divided 25/5.7 but it's saying the answer is incorrect . Can someone explain why and with the math that goes with it, maybe I am setting the equation up wrong

Current Attempt in Progress Your answer is partially correct. 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 600-HF capacitor is 290 V. (a) Determine the energy that is used to produce the flash in this unit. (b) Assuming that the flash lasts for 5.7 ms, find the effective power or "wattage" of the flash. (a) Number 25 Units (b) Number i 4.4 Units W
