Question: A camera flashtube requires 4.1 J of energy per flash. The flash duration is 0.9 ms.
Part A: What power does the flashtube use while it is actually flashing?
Answer= ______ kW
Part B: If the flashtube operates at 200 V, what size capacitor is needed to supply the flash energy?
Answer= _____ µF
Part C: If the flashtube is fired once every 5 s, what is its average power consumption?
Answer= ______ W
