The duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera. (a) if the resistance of the flash lamp is 0.0400 ω during discharge, what is the size of the capacitor supplying its energy? (b) what is the time constant for charging the capacitor, if the charging resistance is 800 kω ?
