The duration of a photographic flash is related to the RC' time constant of the circuit that powers it. For a certain camera the time constant is t= 0.055 µs and the resistance of the flash lamp is R1 = 0.055 Q. Find the capacitance of the capacitor supplying the energy for the flash. Give your answer in µF. Suppose that the camera is modified to use a resistor with a resistance of R, = 795 kN instead. If the capacitor is unchanged, what will the new time constant be in seconds?
