They have moving and fixed plates to determine the capacitance and are generally used in circuit of Transmitters and Receivers, Transistor Radios etc. The main function of a capacitor is to store electric energy in an electric field and release this energy to the circuit as and when required.
By placing capacitors at strategic locations in the circuit, designers can effectively smooth out voltage fluctuations and maintain a consistent voltage level, which is essential for the proper operation of electronic devices.
Therefore we can state a particularly important characteristic of capacitors: The voltage across a capacitor cannot change instantaneously. (6.1.2.7) (6.1.2.7) The voltage across a capacitor cannot change instantaneously. This observation will be key to understanding the operation of capacitors in DC circuits.
When a sudden voltage surge occurs, a capacitor can absorb the excess energy, preventing it from reaching sensitive components and causing harm. This protective function is often utilized in power supply circuits, where capacitors are placed across the power rails to suppress voltage spikes and transients.
Charging and Discharging: The capacitor charges when connected to a voltage source and discharges through a load when the source is removed. Capacitor in a DC Circuit: In a DC circuit, a capacitor initially allows current flow but eventually stops it once fully charged.
W W is the energy in joules, C C is the capacitance in farads, V V is the voltage in volts. The basic capacitor consists of two conducting plates separated by an insulator, or dielectric. This material can be air or made from a variety of different materials such as plastics and ceramics.

Electric Fields and Capacitance | Capacitors | Electronics Textbook
A capacitor''s ability to store energy as a function of voltage (potential difference between the two leads) results in a tendency to try to maintain voltage at a constant level. In other words, capacitors tend to resist changes in voltage. When the voltage across a capacitor is increased or decreased, the capacitor "resists" the change by ...
