What are capacitors used for in a circuit? : r/AskElectronics
These are things a capacitor can do, thanks to its "frequency dependent" characteristics. A very common application of capacitors is in oscillators, where they perform the function of a "timing element". The value (capacitance) of a capacitor will determine the frequency of oscillation (see below). Sometimes you need to "sample" a voltage.
