The dielectrics are mostly solids. Some of the dielectrics are composed of weakly bonded molecules. In such scenarios, along with polarisation, we can also observe that molecules reorient themselves to align their symmetry axes with the field. Dielectric materials are used to store energy. These materials ...

But I have questions to the next two advantages. mosti st. wolfgangDielectric relaxation is the momentary delay (or lag) in the dielectric constant of a material. This is usually caused by the delay in molecular polarisation with respect to a changing electric field in a dielectric medium (e.g., inside capacitors or between two large conducting surfaces). Dielectric relaxation in changing electric fields could be considered analogous to hysteresis in changing magnetic fields (e.g., in inductor or transformer cores).
