16.  A parallel plate capacitor used in a flash for a camera must be able to store 31.0 J of energy when connected to 312 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 7.40×10−3 s, what average power is dissipated in the flashbulb during this time? _____kW
