Question:
A flashing lamp in a Christmas earring is based on an RC discharge of a capacitor through its resistance. The effective duration of the flash is 0.250 s, during which it produces an average 0.500 W from an average 3.00 V.
(a) What energy does it dissipate?
(b) How much charge moves through the lamp?
(c) Find the capacitance.
(d) What is the resistance of the lamp?
