It constantly "drains" the circuit
Capacitor lead length is a consideration in a circuit when the frequency involved is sufficient the make the parasitic capacitance and inductance of the leads important.
Ceramic capacitors can be used anywhere a capacitor having very low internal parasitic inductance is required. Most commonly they are used as powersupply bypass capacitors. They are also sometimes used for coupling capacitors for HF signal amplifiers.
when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .
The manufacturer's data sheet actually recommends using two capacitors with any 3-terminal regulator in the 78xx family: a 0.33µF on the input and a 0.1µF on the output.the input capacitor functions mostly as a filter capacitorthe output capacitor functions mostly as a decoupling capacitorHowever both capacitors should be ceramic capacitors (to reduce parasitic inductance in the capacitors) so that they can operate efficiently at the high frequencies resulting from rapid circuit switching in the load (especially if the load consists of digital logic).
The capacitor on it's own is of no use, it is always used in an RC or LC configuration normally in audio frequency's the RC is used to filter the noise down to earth where the RC circuit have to resonate at the same frequency as the noise, the lower the frequency the larger the value of the capacitor
A: PARASITIC means like a parasite is there to offset the actual circuitry it can be inductance and/or capacitance A capacitor is usually wound in a coil this coil if frequency is hi enough will behave as a small coil has been added to the circuit. Hi frequency PWM capacitors have indeed four lead to reduce not eliminate this inductance
A disc capacitor does exactly the same thing that any other capacitor does, with one difference: it has the lowest value of parasitic inductance of any type of capacitor. As inductance is exactly the opposite property to capacitance, its presence in a capacitor is very undesirable in many applications and can sometimes result in circuit instability.

A: it is the value disc type are small while electrolytic are big in value.The dielectric in a disc capacitor is ceramic, the dielectric in an electrolytic capacitor is a very thin corrosion layer on one of its metal foil plates.The conductive plates in a disc capacitor are two metal thinfilms on opposite sides of the ceramic, the conductive plates in an electrolytic capacitor are one of the metal foil plates and the electrolyte paste between the metal foil plates.A disc capacitor is ready to sell and use as soon as it has been built, an electrolytic capacitor will not work at all when it is first built (it is an electrical short circuit) it must be formed by passing a controlled current through it for several hours to cause corrosion of one of the metal foil plates.The parasitic inductance of a disc capacitor is less than that of any other type of capacitor, the parasitic inductance of an electrolytic capacitor is greater than that of any other type of capacitor. This makes disc capacitors better for use in circuits involving high frequencies and electrolytic capacitors better for use in circuits involving very low frequencies and/or DC.The parasitic resistance of a disc capacitor is extremely high resulting in extremely low leakage, the parasitic resistance of an electrolytic capacitor is low resulting in high leakage. In fact this leakage current in an electrolytic capacitor is essential to keeping it healthy and working in use, without it the corrosion layer dielectric slowly dissolves away into the electrolyte paste. Reversal of polarity of an electrolytic capacitor dramatically hastens this, rapidly removing the corrosion layer and shorting the capacitor resulting in both uncontrolled heating and electrolysis of the water in the electrolyte paste; the extremely rapid generation of gases causes a violent explosion of the electrolytic capacitor!The capacitance of a disc capacitor tends to be low in relation to its physical size compared to other types of capacitor, the capacitance of an electrolytic capacitor is higher in relation to its physical size than any other type of capacitor. This is due mostly to the differences in the thickness of the dielectrics.
In general the length of the leads contributes only a negligible amount to the capacitance of a capacitor. However at high enough frequencies excessive lead length can contribute an undesirable amount of parasitic inductive reactance, causing problems in circuit operation.
The correct spelling is "parasitic."
The Clapp oscillator is a variation of the Colpitts oscillator that includes an additional capacitor in series with the inductor to improve frequency stability. This additional capacitor in the Clapp oscillator helps reduce the effect of the active device's parasitic capacitance, leading to better frequency stability compared to the Colpitts oscillator.
No, sponges are not parasitic.

parasitic
There are several types of capacitors (mainly depending on dielectric: electrolytic, coiled paper, air, ceramic) and for different purposes, the main idea for them is to allow current path for high frequency but a capacitor does not have only capacitance, it does have certain amount of series resistance and inductance depending on design so what works fine in audio frequencies do not do same job for radio frequencies or microwaves as the parasitic inductance becomes relevant. Some other use is tunning or preset where the capacitance is adjustable in order to accomplish resonance with an inductance. A capacitor (series of) is used in a ladder with diodes to rise DC from a low voltage oscillator. Killing HF oscillation is another use avoiding parasitic feedbacks.
yes, they are parasitic
