Is there any downside to using a larger than needed smoothing capacitor?

There are cheaper ways of improving this by a factor of two than doubling the size of the Big Filtering Capacitor (BFC). The downside to a larger BFC is that it will draw larger, shorter current pulses from the input transformer and rectifier. This can cause a number of problems, though most are small, or can be mitigated.

For larger capacitor values, the "plates" may be strips of metal foil, sandwiched around a flexible insulating medium and rolled up for compactness. The highest capacitance values are obtained by using a microscopic-thickness layer of

Capacitor in Electronics

Due to the large size of the farad, capacitors typically have capacitance in microfarads (µF, 10 −6 F), nanofarads (nF, 10 −9 F), and picofarads (pF, 10 −12 F). Dielectric Material A dielectric material is the

Physically Large vs Small Capacitors

So, if both capacitors (small and large) have the same capacitance then one will (more than likely) work up to a larger voltage. A capacitor that is polarized (e.g. electrolytic dielectric) can be physically smaller

A supercapacitor is a specially designed capacitor which has a very large capacitance. Supercapacitors combine the properties of capacitors and batteries into one device. Characteristics Charge time. Supercapacitors have charge and discharge times comparable to those of ordinary capacitors. It is possible to achieve high charge and discharge

How do very small capacitors have large capacitance values?

What i can do to have large capacitance is to have large $epsilon $ value and large Area of metal plate and very thin gap between them. I was thinking of how to bring capacitance to about $ 10mu F$ or $100mu F$ but didn''t have any idea of how to do this without using area of $1m^2$ or more.

OverviewElectrical parametersBackgroundHistoryDesignStylesTypesMaterials

Capacitance values for commercial capacitors are specified as "rated capacitance CR". This is the value for which the capacitor has been designed. The value for an actual component must be within the limits given by the specified tolerance. Typical values are in the range of farads (F), three to six orders of magnitude larger than those of electrolytic capacitors. The capacitan

Is there a physical explanation for why increasing a capacitor''s

This means that a capacitor with a larger capacitance can store more charge than a capacitor with smaller capacitance, for a fixed voltage across the capacitor leads. The voltage across a capacitor leads is very analogous to water pressure in a pipe, as higher voltage leads to a higher flow rate of electrons (electric current) in a wire for a given electrical
