In a circuit, when you connect capacitors in series as shown in the above image, the total capacitance is decreased. The current through capacitors in series is equal (i.e. iT = i1 = i2 = i3= in). Hence, the charge stored by the capacitors is also the same (i.e. QT = Q1 = Q2 = Q3), because charge stored by a plate of any capacitor.
