What?
Power capacitors are passive electronic components that provide a static source of reactive power in electrical distribution systems. They consist of two conducting plates separated by an insulating material called the dielectric.

Function?
Its function is to store the electrical energy and give this energy again to the circuit when
necessary. In other words, it charges and discharges the electric charge stored in it. Besides
this, the functions of a capacitor are as follows: It blocks the flow of DC and permits the flow
of AC.

Reservoir capacitors are used in power supplies where they smooth the output of a full or
half wave rectifier. They can also be used in charge pump circuits as the energy storage
element in the generation of higher voltages than the input voltage.
