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.
In other words, it doesn''t matter if we''re calculating a circuit composed of parallel resistors, parallel inductors, parallel capacitors, or some combination thereof: in the form of impedances (Z), all the terms are common and can be applied uniformly to the same formula.
The top capacitor has no dielectric between its plates. The bottom capacitor has a dielectric between its plates. Because some electric-field lines terminate and start on polarization charges in the dielectric, the electric field is less strong in the capacitor. Thus, for the same charge, a capacitor stores less energy when it contains a ...

Well, that''s very simple. The answer is 230 microfarads. The capacitors combine in parallel, so 10 + 220 equals 230 microfarads. We can keep adding more such as a 100 microfarad capacitor. And the total is just the sum of all of the capacitors. By placing them in parallel we are essentially combining these to form a larger capacitor.

A Definition. As the name implies, a capacitor bank is merely a grouping of several capacitors of the same rating. Capacitor banks may be connected in series or parallel, depending upon the desired rating. As with an individual capacitor, banks of capacitors are used to store electrical energy and condition the flow of that energy.
