The current flowing in this circuit can be calculated using the definition of current, and the charge on the capacitor. Current is the rate of charge passing past a point, which is the same in this case as minus the rate of charge left on the capacitor - the capacitor losing charge corresponds to a positive current flowing from its positive plate to its negative plate.
