(Conductors are equipotentials, and so the voltage across the capacitors is the same as that across the voltage source.) Thus the capacitors have the same charges on them as they would have if connected individually to the voltage source. The total charge (Q) is the sum of the individual charges: [Q=Q_{1}+Q_{2}+Q_{3}.]

Since you only have one possible current path through all the capacitors (and current is just flowing charge) the charge on all 3 capacitors has to be the same. The capacitance of the capacitor indicates how much voltage a particular amount of charge corresponds to Q/C = V. Put more charge into a cap, get a bigger voltage difference.
Here the capacitors look like in series but they are not actually. Capacitors can be said to be in series only if they carry same amount of charge which is not the case here.If you calculate charges will come out to be different.Look at the time constants(R*C) for the first branch and second branch, they are 1ms and 10sec respectively.
For parallel capacitors, the analogous result is derived from Q = VC, the fact that the voltage drop across all capacitors connected in parallel (or any components in a parallel circuit) is the same, and the fact that the charge on the single equivalent capacitor will be the total charge of all of the individual capacitors in the parallel combination.

For an uncharged capacitor connected to ground the other pin (the side of the switch) is also at ground potential. At the instant you close the switch the current goes to ground, that''s what it sees. And the current is the same as when you would connect to ground without the capacitor: a short-circuit is a short-circuit.

In the "Review" its says "When a capacitor is faced with an increasing voltage, it acts as a load: drawing current as it absorbs energy (current going IN THE NEGATIVE side and OUT THE POSITIVE side, like a resistor)", but the 4th picture shows the opposite. Same for the capacitor working as a source.
However, for polar capacitors, such as electrolytic and tantalum, the capacitors must be oriented in the circuit in the correct way. Polar capacitors, in series, must be placed so that the negative electrode of the first capacitor connects to the positive electrode of the second capacitor, and so forth for all capacitors in series.
RC Circuits. An (RC) circuit is one containing a resisto r (R) and capacitor (C). The capacitor is an electrical component that stores electric charge.

As soon as the switch is closed, current flows to and from the initially uncharged capacitor.
