# Problem: A Christmas light is made to flash via the discharge of a capacitor. The effective duration of the flash is 0.23 s (which you can assume is the time constant of the capacitor), during which it produces an average 75 mW from an average voltage of 3.15 V.Part (a). How much energy, in joules, does it dissipate?Part (b). How much charge, coulombs, moves through the light?Part (c). Find the capacitance of the light, in farads.Part (d). What is the resistance, in ohms, of the light?
