A parallel plate capacitor is a device that can store electric charge and energy in the form of an electric field between two conductive plates. The plates are separated by a small distance and are connected to a voltage source, such as a battery. The space between the plates can be filled with air, a vacuum, or a dielectric material, which is an insulator that can be
In low voltage applications, MKP-type capacitors which are made in accordance with metallized polypropylene technology have proved to be most appropriate and also the most cost effective.

In circuits like the one below, I don''t understand how the capacitor can handle voltage spikes. I heard that decoupling capacitors deal with spikes by absorbing more of the voltage, but I don''t understand how the capacitor can reduce the voltage received by the load as the voltage is same between parallel circuits.

High value polarised capacitors typically do not have ideal characteristics at high frequencies (e.g. significant inductance), so it''s fairly common to add a low value capacitor in parallel in situations where you need to worry about stability at high frequencies, as is the case with 78xx regulator ICs such as this.
Cpacitors in parallel Capacitors in a parallel configuration each have the same applied voltage. Their capacitances add up. Charge is apportioned among them by size. Using the schematic diagram to visualize parallel plates, it is apparent that

When connecting capacitors in parallel, there are some points to keep in mind. One is that the maximum rated voltage of a parallel connection of capacitors is only as high as the lowest voltage rating of all the capacitors used in the system. Thus, if several capacitors rated at 500V are connected in parallel to a capacitor rated at 100V, the
In DC power sources, you will see large capacitors in parallel with the output used to filter the DC voltage output. In an "ideal" DC voltage source (like a fully charged car battery), putting capacitors in parallel with the battery terminals will initially change the total circuit current until the capacitor is fully charged wherein the current drawn by the capacitor is negligible.

When 2 capacitors are connected in parallel, the voltage rating will be the lower of the 2 values. e.g. a 10 V and a 16 V rated capacitor in parallel will have a maximum voltage rating of 10 Volts, as the voltage is the same across both capacitors, and you must not exceed the rating of either capacitors.
All capacitors in the parallel connection have the same voltage across them, meaning that: where V 1 to V n represent the voltage across each respective capacitor. This voltage is equal to the voltage applied to the parallel connection of capacitors through the input wires.
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.
High value polarised capacitors typically do not have ideal characteristics at high frequencies (e.g. significant inductance), so it's fairly common to add a low value capacitor in parallel in situations where you need to worry about stability at high frequencies, as is the case with 78xx regulator ICs such as this.
The voltage ( Vc ) connected across all the capacitors that are connected in parallel is THE SAME. Then, Capacitors in Parallel have a “common voltage” supply across them giving: VC1 = VC2 = VC3 = VAB = 12V In the following circuit the capacitors, C1, C2 and C3 are all connected together in a parallel branch between points A and B as shown.
When large current peaks are drawn the capacitor supplied surge energy helps the regulator not sag in output. The white and black bars on the capacitor symbol show that it is a "polar " capacitor - it only works with + and - on the selected ends. Such capacitors are usually "electrolytic capacitors".
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,
