Basically, a capacitor consists of two parallel conductive plates separated by insulating material. Due to this insulation between the conductive plates, the charge/current cannot flow between the plates and is retained at the plates. The plates may be of different shapes like rectangle, square, circular, and can be made into.

Working Principle of a Capacitor: A capacitor accumulates charge on its plates when connected to a voltage source, creating an electric field between the plates. Charging and Discharging: The capacitor charges when connected to a voltage source and discharges through a load when the source is removed.
The construction of capacitor is very simple. A capacitor is made of two electrically conductive plates placed close to each other, but they do not touch each other. These conductive plates
A capacitor is constructed from two conductive metal plates 30cm x 50cm which are spaced 6mm apart from each other, and uses dry air as its only dielectric material. Calculate the capacitance of the capacitor. Then the value of the capacitor consisting of two plates separated by air is calculated as 0.221nF, or 221pF.

The types of capacitors are categorized as follows based on polarization: Polarized; Unpolarized. A polarized capacitor, also known as an electrolytic capacitor, is a crucial component in an electronic circuit. These capacitors are used to achieve high capacitive density. Unpolarized capacitors are preferred over fully charged capacitors.

Depending upon the design, construction, size, and storage capacity of a capacitor, it can be used in a variety of applications.

The electrolytic capacitor construction involves two thin layers of aluminum foil – the plain foil and the etched foil. These two foils are separated by an electrolyte. To set up the polarity of two foils, they are anodized by chemically growing a thin layer of aluminum oxide to form the anode and distinguishes itself from the cathode. In the process of electrolytic capacitor construction

Operation principle and basic construction of capacitors. The basic form of a capacitor is two electrodes (metal plates) facing each other, with a gap in between. When a DC voltage (V) is applied to the two electrodes, electrons will instantly collect on one side, causing that electrode to have a negative charge, while electrons on the other
The construction of capacitor is very simple. A capacitor is made of two electrically conductive plates placed close to each other, but they do not touch each other. These conductive plates are normally made of materials such as aluminum, brass, or copper. The conductive plates of a capacitor is separated by a small distance.
Basically, a capacitor consists of two parallel conductive plates separated by insulating material. Due to this insulation between the conductive plates, the charge/current cannot flow between the plates and is retained at the plates.
All capacitors are formed with the same basic structure. Two parallel metal electrode plates are separated by a non-conductive material called the dielectric. When a voltage exists between these conductive parallel plates, an electric field is present in the dielectric. This field stores energy and produces a mechanical force between the plates.
The capacitance of the capacitor mainly depends upon the surface area of each plate, the distance between two plates and the permitivity of the material between the two plates. Basic circuits of a capacitors mainly includes capacitors connected in series and capacitors connected in parallel.
A numeric value expressing how much charge a capacitor can hold is called the electrostatic capacity, or capacitance (C) for short. Along with resistors and inductors, capacitors make up one of the three major categories of passive components. As many as about two trillion of these devices are being manufactured each year worldwide.
One method used to increase the overall capacitance of a capacitor while keeping its size small is to “interleave” more plates together within a single capacitor body. Instead of just one set of parallel plates, a capacitor can have many individual plates connected together thereby increasing the surface area, A of the plates.
