most variety of modern household and industrial devices, bases its work on the consumption of electric power, regardless of their belonging to the electronics or electrical engineering can not do without in their structural and circuit diagrams as elements of the circuit capacitors.The condenser is a system of a pair (or more) electrodes.Often they have the shape of plates which have been called in the art "electrode".Technologically plates separated by a dielectric (a substance that does not conduct electricity).Its thickness is negligible when compared with the size of the capacitor plates themselves.The attractiveness of the properties of this system is the ability to store an electrical charge.
story begins capacitors Leiden.Back in 1745 in his experiments of physics Ewald Jurgen von Kleist in Germany and Pieter van Musschenbroek from Holland got the original device, called the "Leyden jar".In fact, it was the advent of the first in the history of the capacitor.
course Leyden jar significantly different from the current capacitors.It was corked container filled with water.Inside and outside it oklevali foil.Through the lid of a jar passed into a rod of metal.Despite its unprepossessing, Leyden jar was a pretty powerful properties of condensed charges.The first experiments with capacitors made it possible to artificially obtain a full electric spark.
oscillating circuit, filters, matching circuits of three-phase devices - it's just a short list of the scope of the capacitors.Modern electrical industry has mastered the production of a wide range of devices.Conventional and electrolytic, variables and constants in the richest range of denominations, they find application in various spheres of human activity.Despite this, there is often a need to combine and here is of great importance the correct connection of capacitors to the battery.This allows you to get the most accurate indicators of obtaining the required capacity.
to more specifically address the connection of capacitors should be acquainted with the concept of elektroёmkosti and units for its measurement.High school physics textbook gives a definition of this value as the ratio of the charge accumulated on the plates of the capacitor to the potential difference.Measured elektroёmkost in farads (F).For the SI, it has a physical dimension as a pendant to one volt.
Compound capacitors can be performed in parallel or serial.In a parallel connection method, the value of electric capacity added.Serial communication involves folding the reciprocals of their capacities.It is also possible a mixed compound capacitors.In the chain there are two types of connections simultaneously.
compound mixed-type capacitors are counting on the most suitable for each case the scheme.Depending on the order switching devices in the circuit, the calculation is carried out by bringing the general scheme or a parallel or a serial form.To selected areas of this parallel connection and lead them to a single value.Then have calculated the value of the scheme elektroёmkosti serial connection.You can also perform calculations in the reverse order.
connected capacitors in the circuit requires a study of some of the rules, especially if you intend to use them in conjunction with the inductors, chokes, transformers.If electronic circuits neglect of these rules can only lead to malfunction of the device, the error electricians could cause a serious accident.
