8.2: Capacitance and Capacitors
Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series. In contrast, when capacitors are placed in series, it is as if the plate distance has increased, thus decreasing capacitance.

What happens when plates of a fully charged capacitor are …
If the charged plates are isolated, then pulled apart in a vacuum, they''d keep their charge indefinitely. Dust, humidity, air itself, can all carry off that nonzero charge. Like charges repel, so they spread out over the surface of a conductor. The plate or plate assembly wouldn''t really be pushed apart until we''re talking incredibly dense charges.

Capacitor in Electronics – What It Is and What It Does
When a capacitor is connected to a power source, electrons accumulate at one of the conductors (the negative plate), while electrons are removed from the other conductor (the positive plate). This creates a potential difference (voltage) across the plates and establishes an electric field in the dielectric material between them.
