What are fixed capacitors?
virtually every electronic device uses a capacitor in some way. The capacitors are available as solid capacitors or variable capacitors. Fixed capacitors are those that maintain a constant and unchanging capacity value, its ability to maintain an electric charge. Variable capacitors are characterized by the fact that their capacity value can be modified or changed. The capacitors are available in a number of shapes, sizes and above all capacitance evaluation. In some applications, fixed capacitors are connected together in the series and create what is called a bank with a fixed capacitor. Although they are often used in a resistor tandem to create a timer, fixed capacitors and fixed capacitor banks are also used to supply continuous delivery of the current, which is used to balance the current. This helps to avoid spikes and increases that could occur in the power supply.
There are different types of KOndenzators. In general, they are categorized according to the type of dielectric material used. In principle, the dielectric is a material that does not lead electricity. Dielectric is used in a solid capacitor to insulate or separate materials that perform electricity.
The capacitor is designed with a dielectric sandwich sandwich between two conductive plates. In this way, each board is able to be charged with an electrical current and has the ability to maintain the charge. The difference in the levels of conductive boards allows the existence of an electric field in dielectric.
There are a number of materials such as dielectrics, including paper, plastic, ceramics and others. It is also possible to use air as an insulating layer between conductive plates. Such is a theory behind a vacuum tube.
The evaluation of a solid capacitor capacitance is also affected by the thickness of the dielectrics. In addition, it has a type of material used for a conductive deskY crucial importance, because some materials have a much greater conductivity rate than others.
The history of capacitors can be traced to the 18th century. Peter van Musschenbroek of the University of Leyden in the Netherlands developed what became known as Leyden Jar, early form of the capacitor. Benjamin Franklin is credited later to produce the first flat capacitor.
