The flash on a compact camera stores energy in a 120 μF capacitor that is charged to 220 V. When the flash is fired, the capacitor is quickly discharged through a lightbulb with 5.5 Ω of resistance.
Part A - Light from the flash is essentially finished after two time constants have elapsed. For how long does this flash illuminate the scene?
Part B - At what rate is the lightbulb dissipating energy 260 μs after the flash is fired?
Part C - What total energy is dissipated by the lightbulb?
