A capacitor is an electronic component to store electric charge. It is a passive electronic component that can store energy in the electric field between a pair of conductors called “Plates”. In simple words, we can say that a capacitor is a component to store and release electricity, generally as the result of a chemical action.
Equation 6.1.2.6 6.1.2.6 provides considerable insight into the behavior of capacitors. As just noted, if a capacitor is driven by a fixed current source, the voltage across it rises at the constant rate of i/C i / C. There is a limit to how quickly the voltage across the capacitor can change.
As long as the current is present, feeding the capacitor, the voltage across the capacitor will continue to rise. A good analogy is if we had a pipe pouring water into a tank, with the tank's level continuing to rise. This process of depositing charge on the plates is referred to as charging the capacitor.
A capacitor is made up of two metallic plates with a dielectric material (a material that does not conduct electricity) in between the plates. And there’s actually no more magic to it. It’s that simple and you can even make your own capacitor by using two sheets of aluminum foil with a piece of paper in between.
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.
A good analogy is if we had a pipe pouring water into a tank, with the tank's level continuing to rise. This process of depositing charge on the plates is referred to as charging the capacitor. For example, considering the circuit in Figure 8.2.13 , we see a current source feeding a single capacitor.

Altering any two of these values alters the the value of its capacitance and this forms the basis of operation of the variable capacitors. Also, because capacitors store the energy of the electrons in the form of an electrical charge on the plates the larger the plates and/or smaller their separation the greater will be the charge that the capacitor holds for any given voltage across its ...

Electrolytic capacitors consist of two electrodes (anode and cathode), a film oxide layer acting as a dielectric and an electrolyte. The electrolyte brings the negative potential of the cathode closer to the dielectric via ionic transport in the electrolyte [7] (see Fig. 2).The electrolyte is either a liquid or a polymer containing a high concentration of any type of ion, although …
