dielektrilistele

Dielektrilistele refers to materials that are electrically insulating and can be polarized by an applied electric field. This polarization occurs when the positive and negative charges within the dielectric material shift slightly from their equilibrium positions, creating an electric dipole. When an external electric field is applied, these dipoles align themselves with the field, effectively reducing the strength of the electric field within the material. This property makes dielectrics crucial components in electronic devices, particularly in capacitors, where they are used to store electrical energy.

The ability of a dielectric material to be polarized is quantified by its dielectric constant, also known as relative permittivity. A higher dielectric constant indicates that the material can store more electrical energy for a given electric field strength. Dielectric materials are also used as insulators in electrical wiring and in high-voltage equipment to prevent electrical current from flowing where it is not intended. Common examples of dielectric materials include ceramics, plastics, glass, and mica. The behavior of dielectrics under electric fields is a fundamental concept in electromagnetism and is described by the principles of electrostatics.
