When I connect two charged capacitors side by side, what will be
Say, I have two charged capacitors, one 3mF and one 2mF. Charges on all plates for capacitors in series must be equal. Q=CV for each capacitor. The potential difference between the two outer plates will be either $30+20 = 50, rm V$ or $30 -20 =10,rm V$ depending on the sign of the charges on the two inner plates.

Charge Distribution on a Parallel Plate Capacitor
Ignore inner and outer surfaces. There is just one surface. Imagine a single, infinite plane with some positive charge density. You can easily show there would be an electric field of constant strength*, perpendicularly out of the plane all the way to infinity on both directions.. Now imagine a single, infinite plate with the same negative charge density.
The energy stored in a capacitor is actually stored
Energy stored in a Capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up. So, correct answer is "between the plates"...

Why do capacitors in series not just act as one capacitor with the
Let''s say we have capacitors A and B in series with two plates each (1 &2), 1 A 2 - 1 B 2. If you draw electrons away from capacitor A''s plate 1, it will leave off a positive charge to that capacitor plate. Due to the newly created electric field, this invites electrons to flow from Capacitor B''s plate 1 to Capacitor A''s plate 2.

6 FAQs about [Capacitor in series with outer charged plates]
How are capacitor plates charged in a series circuit?
The capacitor plates in between are only charged by the outer plates. In a series circuit, the total voltage drop equals the applied voltage, and the current through every element is the same. The charge on every capacitor plate is determined by the charge on the outermost plates and is limited by the total equivalent capacitance of the circuit.
How are two capacitors connected in series?
Two capacitors are connected in series (one after the other) by conducting wires between points and Both capacitors are initially uncharged. When a constant positive potential difference is applied between points and the capacitors become charged; the figure shows that the charge on all conducting plates has the same magnitude.
Can two capacitors in series be considered as 3 plates?
In the non-ideal case, of course, this does not apply. Two capacitors in series can be considered as 3 plates. The two outer plates will have equal charge, but the inner plate will have charge equal to the sum of the two outer plates.
How many plates can a capacitor have?
Two capacitors in series can be considered as 3 plates. The two outer plates will have equal charge, but the inner plate will have charge equal to the sum of the two outer plates. For various practical reasons, you would probably want resistors in parallel to help balance the DC charge on the capacitors.
Why do all capacitors have the same electrical charge?
Then, Capacitors in Series all have the same current flowing through them as iT = i1 = i2 = i3 etc. Therefore each capacitor will store the same amount of electrical charge, Q on its plates regardless of its capacitance. This is because the charge stored by a plate of any one capacitor must have come from the plate of its adjacent capacitor.
Why does a series capacitor have a Q?
This occurs due to the conservation of charge in the circuit. When a charge Q in a series circuit is removed from a plate of the first capacitor (which we denote as − Q), it must be placed on a plate of the second capacitor (which we denote as + Q), and so on.
