What is dielectric constant? How to obtain data on relative dielectric constant and dielectric loss using ZAHNER electrochemical workstation?

Relative dielectric constant, also known asrelative permittivityRelative permittivity orspecific inductive capacityIt is an important property of an electrically insulating (dielectric) material. Generally speaking, the magnitude of the dielectric constant is determined by the flat capacitor filled with the dielectric materialcapacitorThe capacitance valuecapacitanceThe ratio between the capacitance values of an ideal flat capacitor with the same area and no dielectric under vacuum, represented by lowercase Greek letterskappaThe formula isκ=c/c₀orε_r=ε/ε₀The dielectric constant of vacuum is1.
