Question: Three capacitors are connected in series to an ideal voltage source and charged, as shown in Figure 1 above. The capacitors are identical except that capacitor x has air between its plates, whereas capacitors Y and ?bar (Z) each have a dielectric slab of dielectric constant κ>1 between their plates.
The answer to this comes from considering what is capacitance: it is the number of coulombs (C) of charge that we can store if we put a voltage (V) across the capacitor. Effect 1: If we connect capacitors in series, we are making it harder to develop a voltage across the capacitors. For instance if we connect two capacitors in series to a 5V ...

Capacitors store charge, and develop a voltage drop V across them proportional to the amount of charge Q that they have stored: V = Q/C. The constant of proportionality C is the capacitance (measured in Farads = Coulombs/Volt), and determines how easily the capacitor can store charge. Typical circuit capacitors range from picofarads (1 pF = 10-12

In the normal case, this means that if charge flows out one lead it must flow into the lead of another capacitor (the voltage source obeys KCL) so all the capacitors must have equal charge. In the non-ideal case, of course, this does not apply. Two capacitors in series can be considered as 3 plates.
