dielektrikkina
A dielectric material is an insulating substance that responds to electric fields by polarizing its internal charge distribution. In electrical devices, dielectrics separate conductive regions, allow energy storage, and provide insulation to reduce unwanted current flow. Dielectrics are essential in capacitors, where they increase energy storage and modify the device’s electric field.
The key property of a dielectric is its permittivity, often expressed as ε = ε0εr, where ε0 is
Common dielectric materials range from air and vacuum to polymers (such as polyethylene and polyimide), ceramics
Applications span capacitors, cable insulation, transformer windings, and semiconductor devices where thin dielectric films serve as
