Question

The duration of a photographic flash is related to an RC time constant, which is 0.12 us during the flash discharge for a certain camera.

td = 0.12 us

R = 0.048 ohm

(a) If the resistance of the flash lamp is 0.048 ohm during discharge, what is the size of the capacitor supplying its energy in uF?

(b) What is the time constant for charging the capacitor, if the charging resistance is 800.0 kOhm in s?
