Intuitively, why does putting capacitors in series decrease the equivalent capacitance?

One way to look at it -- though perhaps more from an electronics than a physics perspectice -- is to not think of a capacitor as a thing that stores charge.Sine the entire component is electrically neutral when viewed from outside, the total amount of charge inside it is always the same; it just gets redistributed in ways that need not concern us at …
