A parallel plate capacitor used in a flash for a camera must be able to store 32.6 J of energy when connected to 301 V. (Most electronic flashes actually use a 1.50- to 6.00-V battery, but increase the effective voltage using a dc–dc inverter.) Assuming the capacitor completely discharges to produce a flash in 4.20×10−3 s, what average power is dissipated in the flashbulb during this time? (need answer in kW)
