dielektriskos

Dielektriskos, also known as dielectric, refers to a material that does not conduct electricity under normal conditions. Dielectrics are characterized by their ability to become polarized when an electric field is applied, which allows them to store and release electrical energy. This property makes dielectrics essential in various electrical and electronic applications.

Dielectric materials are typically insulators, meaning they have high electrical resistance. Common examples of dielectrics include ceramics, glass, and certain plastics. These materials are used in capacitors, where they serve as the insulating layer between conductive plates, allowing for the storage of electrical charge.

In addition to their insulating properties, dielectrics also exhibit other useful characteristics. They can withstand high voltages without breaking down, making them suitable for applications in high-voltage environments. Dielectrics also have low electrical conductivity, which minimizes energy loss in electrical systems.

The dielectric constant, often denoted by the symbol ε, is a measure of a material's ability to store electrical energy in an electric field. This constant is dimensionless and varies depending on the material. For example, the dielectric constant of vacuum is approximately 1, while that of water is around 80.

Dielectrics play a crucial role in modern technology, from the capacitors in electronic circuits to the insulators in power transmission lines. Their ability to store and release electrical energy efficiently makes them indispensable in various electrical and electronic devices.
