The light from a cameras electronic flash is produced when a highvoltage obtained by charging a capacitor is applied to electrodesin a xenon-filled flash bulb.
(a) to what voltage would a 60-microfarad capacitor be charged by a6mA current lasting 10 seconds?
(b) if the bulb when conducting current and emitting light acts asan 0.1-ohm resistor what is the time constant for discharging this capacitor?
