When capacitors are connected together in parallel the total or equivalent capacitance, CT in the circuit is equal to the sum of all the individual capacitors added together. This is because the top plate of capacitor, C1 is connected to the top plate of C2 which is connected to the top plate of C3 and so on.
Well, just replace C1 in the circuit above with a 100 µF and a 47 µF capacitor in parallel, and you end up with a total capacitance of 147 µF. Another typical place where you’ll see capacitors connected in parallel is with microcontroller circuits. Microcontroller chips often have several power pins.
The goal of mounting capacitors in parallel is to re-duce ESL and ESR, and thereby be more effective in filtering out high-frequency noise. However, it is not the only solution. An obvious alternative is to use a single low-ESL capacitor instead of the pair of parallel capacitors.
which means that the equivalent capacitance of the parallel connection of capacitors is equal to the sum of the individual capacitances. This result is intuitive as well - the capacitors in parallel can be regarded as a single capacitor whose plate area is equal to the sum of plate areas of individual capacitors.
One example are DC supplies which sometimes use several parallel capacitors in order to better filter the output signal and eliminate the AC ripple. By using this approach, it is possible to use smaller capacitors that have superior ripple characteristics while obtaining higher capacitance values.
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.

Why does the distance between the plates of a capacitor affect …
If the capacitor is charged to a certain voltage the two plates hold charge carriers of opposite charge. Opposite charges attract each other, creating an electric field, and the attraction is stronger the closer they are. If the distance becomes too large the charges don''t feel each other''s presence anymore; the electric field is too weak. Share. Cite. Follow answered …

Capacitors in parallel | Applications | Capacitor Guide
Capacitors are devices used to store electrical energy in the form of electrical charge. By connecting several capacitors in parallel, the resulting circuit is able to store more energy since the equivalent capacitance is the sum of individual capacitances of all capacitors involved. This effect is used in some applications. DC power supplies ...

A large capacitor like the 2200 uF act as a "reservoir" to store energy from the rough DC out of the bridge rectifier. The larger the capacitor the less ripple and the more constant the DC. When large current peaks are drawn the capacitor supplied surge energy helps the regulator not sag in output.

Role of capacitors in amplifier
The capacitor is an open circuit for the DC voltage/current from the previous stage, but it allows the higher frequency AC signal to pass to the next stage. If you remove the entry capacitor to a new stage, the DC voltage from the previous stage will displace the operating point of the new stage, which will not operate properly. You will probably get noise at the output; i.e. the unit …
