The peak voltage is actually higher, and the peak voltage is what charges the capacitor. If the secondary windings operate at 12V RMS, then the capacitor will charge to a peak of about 17V. Thus, at the peak, there is 5V of dropout. On each cycle, the capacitor charges to the peak voltage. Then, it discharges as the regulator draws current from

How capacitors work. Now that we know what a capacitor is, let''s talk about how it works. When a voltage is applied to a capacitor, it starts charging up, storing electrical energy in the form of electrons on one of the
Larger capacitors respond well to DC signals, but tiny chip capacitors offer a far higher frequency response. Conclusion. If a capacitor is larger, its charge/discharge rate will be slower. Smaller capacitors have higher resonance points due to their lower ESL and are thus better for high frequency bypassing. The design of the cap can help

In the highly idealized capacitors of this chapter, the linear dimensions of the plates (length and breadth, or diameter) are supposed to be very much larger than the separation between them. This in fact is nearly always the case in real capacitors, too, though perhaps not necessarily for the same reason.
