An uncharged series RC circuit is to be connected across a battery. For each of the following changes, determine whether the time for the capacitor to reach 9 0 % of its final charge would increase, decrease, or remain unchanged
When the battery is first connected to the series of capacitors, it produces charge -q on the bottom plate of capacitor 3. That charge then repels negative charge from the top plate of capacitor 3 (leaving it with charge +q). The repelled negative charge moves to the bottom plate of capacitor 2 (giving it charge -q).
Capacitors in series? Capacitors in series have identical charges. We can explain how the capacitors end up with identical charge by following a chain reaction of events, in which the charging of each capacitor causes the charging of the next capacitor. We start with capacitor 3 and work upward to capacitor 1.

The force on each electron particle is proportional to the sum of all the "arrows" of where you place it. You can see that on the point where your electron in your drawing is, there are no field components from the capacitor, so the capacitor has virtually no effect on it.
Lets assume from the start that in a single capacitor everything is neutral, and that nothing is polarized. Electrons and protons are evenly distributed on both sides of a capacitor. Then you apply a voltage across the capacitor, which separates X amounts of electrons (aka the -q) from the protons (aka the +q).

For example, we can''t use the series capacitors formula to find the equivalent capacitance of the combination, or the series impedance formula to find the equivalent impedance of the combination. "Why must the incoming and outgoing current in a battery always be equal?" -- because, like gravity, it''s the law.
