The capacitor is used to store the charge applied to it.
This stored charge can be used to absorb voltage spikes and voltage drops.
Answer
It's a misconception that a capacitor stores charge. In fact, it stores energy. The net charge on a fully-charged capacitor is the same as on a fully discharged capacitor.

∙ 8y ago1.A capacitor stores accumulated charges as voltage.
2.The storing and discharging of these charges help regulate voltage in circuits.
3.As the switching frequency of storing or discharging increases the 'frequency dependant resistance' or reactance decreases and appears as a short circuit at infinite frequency.
4.The capacitor appears as a open circuit at zero frequency.

What is function of capacitor in 555 IC?
the capacitor and its associated resistor set the time constant.
What is the principle of function generator?
with the help of function generator we found wave in oscilloscope
What is function of emitter bypass capacitor?
A: THE EMITTER resistor sole function is to provide stability if it is by passed by a capacitor then this resistance will change due to frequency since as frequency increases the impedance decreases. The total gain will change accordingly
What is the function of a bypass capacitor in an amplifier?
Bypass capacitors are used to bypass (shunt) unwanted signals to the ground. A common use is in power supplies where a bypass capacitor is connected in parallel with the main filter capacitor to shunt noise and other high frequency interference to ground which the main capacitor may not be able to do.
What is the purposeof the capacitor between emitter to ground?
The purpose of capacitor between emitter to ground is to permit the transis tor to function in the depletion region without the elimination of the Q point.
What is the function of a capacitor in a washing machine?
The function of a capacitor in a washing machine is to store a charge. This charge is what starts the washer.
What two facctors determine the capacitive reactance of a capacitor?
The reactance of a capacitor is a function of -- the capacitance of the capacitor -- the frequency of the voltage across the capacitor

Function of dielectric in a capacitor?
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
What is the function of fixed capacitor?
A fixed capacitor has a fixed capacitance (within certain limits influenced by aging). So it can fulfill any function that a (variable) capacitor fulfills, beside changing its capacitance easily (e. g. by turning a wheel).

What effect does the series resistance of a capacitor used in a capacitor filter have on diode current and ripple voltage compared with an ideal capacitor of no resistance?
The effective resistance of the capacitor reduces the ripple current through the capacitor making it less effective in its function of smoothing the voltage. But if the capacitor filter is fed by a transformer and diodes, the resistance of the transformer exceeds that of the capacitor.
