The so-called dielectric process has the purpose of allowing a significant increase of the effect caused by the capacitance, since each capacitor is composed of two different plates. The first circuit of the capacitor consists of the resistor R, a capacitor C and a properly tensioned battery that must always remain activated, all of which are connected together in series. It should be understood that if a large unit is required, capacitors with capacitance at the picofarad scales, represented by PF, and microfarad, indicated by MF, must be used.

In the circuit, the current is common to all elements, since they are influenced by it. If there is a capacitor, the battery will result in an inadequate current. According to the component inserted between the plates of the capacitor, which consists of the dielectric, the categories of the same end up being determined in oil, paper, ceramic, polyester, polystyrene or electrolytic. Each type of capacitor has a specific application, varying according to the frequencies of the signals that will be used, always having to check the maximum voltage that can be supported without breaking the dielectric.
