The flash on a compact camera stores energy in a 120 μF capacitor that is charged to 220V. When the flash is fired, the capacitor is quickly discharged through a lightbulb with 6.0 Ω of resistance. At what rate is the lightbulb dissipating energy 300 μs after the flash is fired? What total energy is dissipated by the lightbulb?
