dielektrikumok
Dielektrikumok, also known as dielectric materials, are electrical insulators that can be polarized when subjected to an electric field. This polarization means that the positive and negative charges within the material slightly shift their positions, creating an internal electric field that opposes the external one. This property makes dielectrics crucial in the construction of capacitors, where they are placed between conductive plates to increase capacitance and store electrical energy.
The effectiveness of a dielectric material is measured by its dielectric constant, which is the ratio of
Dielectrics are also used for electrical insulation to prevent short circuits and protect electrical components from
