Negative voltage in capacitor when + side is connected to
I don''t understand why we get a negative voltage (-4.7 V) from a capacitor''s negative pole when we apply 0 V to a capacitor''s positive pole. As I figured out, this is used in a transistor flip-flop.
Parallel Capacitors with different voltages
So if you connect the two capacitors together with ideal wires then at that instant the two capacitors will still have their original, different voltages. But they are connected in parallel, so by definition they must have the same voltage across them.

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 …
