Camera physics question!?

An electronic flash attachment for a camera produces a flash by using the energy stored in a 840-F capacitor. Between flashes, the capacitor recharges through a resistor whose resistance is chosen so the capacitor recharges with a time constant of 2.7 s. Determine the value of the resistance.
