How to adjust the two ends of the capacitor
You have the right general idea, but you can''t just consider the two capacitors as one 3F capacitor. Just before the switch is closed, the 2F capacitor will be fully charged and (I presume) the 1F capacitor is fully discharged. So when the switch is closed, the 2F capacitor will discharge and the 1F capacitor will charge. - Download [PDF]

Charging and Discharging a Capacitor
For two different circuits, each with one of the above capacitors, the circuit with the second capacitor (with more surface area) has a current that stays more constant than the first. The larger capacitor also ends up with a greater amount of charge on its plates. This is because fringe field magnitude is inversely proportional to plate area, as shown in the equation …

Current on both sides of a capacitor
$begingroup$ That the current on both leads of a capacitor is the same is an approximation that characterizes lumped two-poles. In general, however, a conductive structure with the typical shape of a capacitor does not conserve current this way if it can radiate electromagnetic waves into free space, but that''s very hard to calculate, so for technical …
8.3: Capacitors in Series and in Parallel
The series combination of two or three capacitors resembles a single capacitor with a smaller capacitance. Generally, any number of capacitors connected in series is equivalent to one capacitor whose capacitance (called the equivalent capacitance ) is smaller than the smallest of the capacitances in the series combination.
