Resistors, coils and capacitors – these are the three largest groups of passive electronic devices. They are used in various types of devices. They will certainly be useful if you are building your own and more advanced electronic project!
Capacitors are electronic passive components that store energy in an electric field. Such devices can be divided into two types: polar capacitors and non-polar capacitors. For some capacitors, the direction in which they are connected to the circuit is important. Of course, different capacitors will differ in many detailed technical parameters.
However, it can be said that a capacitor is a component with two pins. There is a certain capacitance between any two electrical conductors that are close to each other, but a capacitor is a component designed to give a specific capacitance between its leads. such components, like other passive components, have a huge number of applications in passive and active systems. Capacitors are used as filters or elements of resonant circuits. The capacitor is one of the basic elements of electronic designs.

There are many types of these components that are commonly used in electronics. Most capacitors contain at least two electrical conductors , often in the form of metal plates or foils separated from each other by a dielectric. The earliest forms of capacitors originated in the 1740s, when European experimenters discovered that electrical charge could be stored in glass jars filled with water, which became known as Leyden jars.
A capacitor consists of two conductors separated by a non-conducting dielectric . It can be a vacuum or any insulator. Examples of dielectrics used in these elements are glass, air, paper, plastic, ceramics, etc. According to Coulomb's law, the charge on one plate exerts a force on the charge carriers in the other plate, attracting the opposite charge and repelling carriers with the same charge. In this way, an opposite charge will be induced on the second plate. Conductors therefore maintain charges of equal and opposite magnitude on their surfaces. The presence of the dielectric prevents charge from flowing and maintains the electric field.
Many different types of capacitors are commercially available. They differ in the type of dielectric, cover structure and housing type. All these elements influence the characteristics of the element and the scope of its application. Values available range from very low (in the single picofarad range) to supercapacitors with capacitances up to about 5 kF. Typically, above about 1 microfarad, electrolytic capacitors are almost exclusively used due to their small size and low cost compared to other types of comparable capacity, unless their relatively poor stability, life and occurrence of polarization make them unsuitable for given application.
The basic parameter that describes a capacitor is its capacity . This is a value expressed in farads; it tells us how much electric charge can fit in a given element. The capacity is selected for the specific application of a given capacitor. The second parameter is the maximum operating voltage. Each capacitor, due to its structure, based on a thin dielectric layer between the conductive plates, can only operate up to the permissible voltage level. If it is exceeded, the dielectric may break down and the capacitor plates may short-circuit. In a given system, the maximum rated voltage of the capacitor should be no lower than the voltage occurring on its plates at any time, including overvoltages and even momentary voltage increases.
Today, capacitors are widely used in electronic circuits to block direct current, allowing alternating current to flow. In analog systems, capacitors are part of filters, in resonant circuits they tune the systems to specific frequencies, and in electrical energy transmission systems they stabilize the voltage and power flow. The energy storage property of capacitors was also used as a dynamic memory element in early computers.
A capacitor is made of two conductors separated by a dielectric that conducts electricity poorly. The effect of a capacitor is its capacitance. There is some capacitance between any two nearby electrical conductors in a circuit. A capacitor is therefore an element that adds capacitance to a circuit. See the full guide on Botland Blog .
A decrease in nominal capacity or a deviation in the efficiency indicator means that the capacitor you are measuring is not working properly. Routine measurement of an electronic capacitor will be indicated by UNI-T capacitance meters or oscilloscopes .
Capacitors are important components of power circuits. These may be filtering or energy storage capacitors. In devices operating at low frequencies, they can also perform blocking and coupling functions. You can also find capacitor kits at Botland.
