Consider the camera flash in Problem 21. If the flash really discharges according to Eq. (18-26), then it takes an infinite amount of time to discharge. When Problem 21 assumes that the capacitor discharges in 4.0 × 10−3s, we mean that the capacitor has almost no charge stored on it after that amount of time. Suppose that after 4.0 × 10−3 s the capacitor has only 1.0% of the original charge still on it.
(a) What is the time constant of this RC circuit?
(b) What is the resistance of the flashbulb in this case?
(c) What is the maximum power dissipated in the flashbulb?
