A capacitor can store electric energy when it is connected to its charging circuit. And when it is disconnected from its charging circuit, it can dissipate that stored energy, so it can be used like a temporary battery.
A capacitor is created out of two metal plates and an insulating material called a dielectric. The metal plates are placed very close to each other, in parallel, but the dielectric sits between them to make sure they don't touch.
A capacitor works on the principle that the capacitance of a conductor increases appreciably when an earthed conductor is brought near it. Hence, a capacitor has two plates separated by a distance having equal and opposite charges.
Capacitor- is a device for temporarily storing electric charge. In 1745, the Leyden jar was competitively invented by Ewald Jurgen von Kleist - 4 Nov 1745. Pieter van Musschenbroek produced the first working example in Jan 1746, with the name coming from Leiden University.
Wet tantalum capacitors have been used in space applications for over 40 years, from the early days of the manned space flight programs.
A capacitor is a two-terminal component that consists of two electrically conductive plates that are separated by an insulative material called the dielectric. The two conductive plates are like the air on the inside and outside of the balloon, and the dielectric material is the rubber balloon that separates them.
Capacitor is generally used to store the charge. The charge is stored in the form of “electrical field”. Capacitors play a major role in many electrical and electronic circuits. The basic construction of all capacitors is of two parallel metal plates separated by an insulating material (the dielectric).
Capacitors are electronic components that are used to temporarily store energy in circuits, and they do so by storing electric charge in two conductive plates. When each plate has a different amount of stored charge, the potential difference between them creates an electric field.

Basic electronics capacitor
Type of capacitor
Aluminum electrolytic capacitors are polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminum foil with an etched surface. The aluminum forms a very thin insulating layer of aluminum oxide by anodization that acts as the dielectric of the capacitor. A non-solid electrolyte covers the rough surface of the oxide layer, serving in principle as the second electrode (cathode) (-) of the capacitor. A second aluminum foil called “cathode foil” contacts the electrolyte and serves as the electrical connection to the negative terminal of the capacitor.

Small engine ignition system
Capacitor discharge ignition (CDI) or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors, motorcycles, lawn mowers, chainsaws, small engines, turbine-powered aircraft, and some cars. It was originally developed to overcome the long charging times associated with high inductance coils used in inductive discharge ignition (IDI) systems, making the ignition system more suitable for high engine speeds. The capacitive-discharge ignition uses capacitor discharge current to the coil to fire the spark plugs.

Type of capacitor
An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor. Because of their very thin dielectric oxide layer and enlarged anode surface, electrolytic capacitors have a much higher capacitance-voltage (CV) product per unit volume than ceramic capacitors or film capacitors, and so can have large capacitance values. There are three families of electrolytic capacitor: aluminium electrolytic capacitors, tantalum electrolytic capacitors, and niobium electrolytic capacitors.
