Advantages of using Capacitors in Parallel. Connecting capacitors in parallel results in more energy being stored by the circuit compared to a system where the capacitors are connected in a series.

The basic rule for capacitors in parallel circuits is incredibly straightforward: the total capacitance (CTOT) is simply the sum of the individual capacitances. This can be formally represented by the equation: CTOT = C 1 + C 2 + C 3 + + C n. The reason behind the simple addition rule lies in the physics of the capacitors themselves.
Measuring a capacitor in series or parallel mode can provide different results. How the results differ can depend on the quality of the device, but the thing to keep in mind is that the capacitor''s measured value most closely represents its effective value when the more suitable equivalent circuit, series or parallel, is used.

One important point to remember about parallel connected capacitor circuits, the total capacitance ( CT ) of any two or more capacitors connected together in parallel will always be GREATER than the value of the largest capacitor in the group as we are adding together values.
We can also define the total capacitance of the parallel circuit from the total stored coulomb charge using the Q = CV equation for charge on a capacitors plates. The total charge QT stored on all the plates equals the sum of the individual stored charges on each capacitor therefore,

As the voltage, ( V ) is common for parallel connected capacitors, we can divide both sides of the above equation through by the voltage leaving just the capacitance and by simply adding together the value of the individual capacitances gives the total capacitance, CT.
Since the capacitors are connected in parallel, they all have the same voltage V across their plates. However, each capacitor in the parallel network may store a different charge.
