What Is a Capacitor and What Is It Used For?

As a direct current flows into a capacitor, it charges with energy and releases an alternating current flow back into the circuit. Most capacitors have a positive and negative terminal in the form of legs, pads, or plates. Current flows into one of these legs, through the capacitor''s body, and out of the other leg.

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 compared to a capacitor with a better (lower loss) dielectric and this is also a significant trade-off.

Best way to test large capacitors? | All About Circuits

With a capacitor this large you can test it for capacitance by shorting the leads then charging the capacitor through a 1k resistor while watching the voltage across the capacitor with a voltmeter. The time it takes the capacitor to reach 6.3 volts is the time constant of the circuit in seconds.

Is a very large capacitor the same as a short circuit?

If you are on transient domain (ie: calculating the circuit reaction to a key switching), the capacitor is an short until it is fully loaded. Then it will work as an open circuit like the DC model. If you are dealing with AC, a very large capacitor (a capacitor with theoretical infinite capacitance) is an short circuit.

Are there large-range variable capacitors?

The variable capacitor you want is in a filter/oscillator, right? Please edit the question to make that clear. Emulate the large capacitor using a small one and an op-amp based impedance multiplier with gain <1, ie. so that the output capacitive conductance is much higher than the conductance of the variable capacitor you''re using.

Capacitor Size Guide for Car Audio

Although the rule of thumb is to use 1 Farad capacitor for 1,000 watts RMS, you can still use a bit bigger capacitor. Using a 2 or 2.5 Farads capacitor may benefit your car''s audio with extra power and charge. However, you should keep in mind that an extra big capacitor can do more harm than any benefit.
