Another common capacitor type is the film capacitor, which features very low parasitic losses (ESR), making them great for dealing with very high currents. There''s plenty of other less common capacitors. Variable capacitors can produce a range of capacitances, which makes them a good alternative to variable resistors in tuning circuits. Twisted ...
How Capacitors Work
A 1-farad capacitor can store one coulomb (coo-lomb) of charge at 1 volt. A coulomb is 6.25e18 (6.25 * 10^18, or 6.25 billion billion) electrons. One amp represents a rate of electron flow of 1 coulomb of electrons per second, so a 1-farad capacitor can hold 1 amp-second of electrons at 1 volt. A 1-farad capacitor would typically be pretty big.
Why is there a capacitor in the feedback path of a comparator, …
(The super-capacitor in this case is a 2.7V one). I have two questions: What is C1 for? I presume stability of the op-amp, but am not sure. What is R2 for? That doesn''t seem to be doing much. It isn''t acting as a voltage divider, and the op-amp input is already high-impedance. I am guessing it is something to do with circuit stability, but am ...
Capacitor Cheat Sheet
The cost: The original G&L scheme calls for alternate pot values, but the project here uses the 500K pots found in most humbucker guitars, so all you need are wire, solder, and a few capacitors. On a three-knob guitar, you wind up with one master volume control and two master tone controls, but you sacrifice individual volume controls for each pickup.On a four …

Is it Time to Replace the Air Conditioner Capacitor?
Although the capacitor is just a fraction of the size of the unit it powers, when it stops working, the entire system can shut down. When an HVAC capacitor fails or misfires, your unit may stop blowing cool air or refuse to start at all. The capacitor may look like a battery, but it does far more than simply turn your unit off and on.

Capacitor Basics: How do Capacitors Work?
As capacitors store energy, it is common practice to put a capacitor as close to a load (something that consumes power) so that if there is a voltage dip on the line, the capacitor can provide short bursts of current to resist that voltage dip.

How important is it to have decoupling capacitors on the same side of the PCB as the IC? I am desperately short of space in a design, and it would really help to put the caps on the bottom side.. I guess it can''t be that bad, because BGAs seem to use this technique in designs that are much faster than mine (a 67MHz MCU).. But then questions such as Decoupling caps, PCB …

If you put an electrolytic capacitor in the wrong way momentarily it will sustain. As a matter of fact when you are using it to bypass AC it does receive reverse polarity for smaller amounts of time. However if you reverse the polarity for longer duration with significant voltage across it, it will explode !

18.5 Capacitors and Dielectrics
For a given capacitor, the ratio of the charge stored in the capacitor to the voltage difference between the plates of the capacitor always remains the same. Capacitance is determined by the geometry of the capacitor and the materials that it is made from. For a parallel-plate capacitor with nothing between its plates, the capacitance is given by
Why do capacitors lose capacitance in series?
Capacitance, however, is not a measure of maximum charge: it measures the charge/voltage ratio in a component. A 2F capacitor will show 1V across it''s terminals when charged with 2C. This makes capacity and capacitance uncomparable, since you can always (assuming a undestructible capacitor) put more charge in a capacitor by increasing it''s voltage.

However, the capacitor may have two parallel plates but only one side of each plate is in contact with the dielectric in the middle as the other side of each plate forms the outside of the capacitor. If we take the two halves of the plates and join them together we effectively only have "one" whole plate in contact with the dielectric.
