(Conductors are equipotentials, and so the voltage across the capacitors is the same as that across the voltage source.) Thus the capacitors have the same charges on them as they would have if connected individually to the voltage source. The total charge (Q) is the sum of the individual charges: [Q=Q_{1}+Q_{2}+Q_{3}.]

If a capacitor is connected in series with a battery, then the potential difference between the plates is fixed and equal to the voltage of the battery. Therefore, if the capacitance changes, then the charge on the capacitor plates must change as well in order to keep the potential difference between the plates constant.

If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse proportion.

For parallel capacitors, the analogous result is derived from Q = VC, the fact that the voltage drop across all capacitors connected in parallel (or any components in a parallel circuit) is the same, and the fact that the charge on the single equivalent capacitor will be the total charge of all of the individual capacitors in the parallel combination.

The fundamental current-voltage relationship of a capacitor is not the same as that of resistors. Capacitors do not so much resist current; it is more productive to think in terms of them reacting to it.

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 …
So capacitors are connected in parallel if the same potential difference is applied to each capacitor. Let C1, C2, and C3 be 3 capacitors. And we connect these capacitors in parallel this way, in order to apply the same potential difference to each one of them, which is what we call parallel connection.

then why is there no potential difference between the two capacitors. It''s not quite clear what you mean here but do understand that charged capacitors are electrically neutral.. When a capacitor is "charged", it is not electrically charged, it is energy charged in the same sense as when we say a battery is charged.. There is nothing mysterious about two …
