Hey sistah!
Here's your answer!!
✔️WHAT ARE DIELECTRICS?
➡ Dielectrics are the substances that are poor conductor or insulators of electricity, but an efficient supporter of electrostatic fields.
➡ Dielectrics have no loosely bound electrons, and so no current flows through them.
➡ When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization. Because of dielectric polarization, positive charges are displaced toward the field and negative charges shift in the opposite direction.
➡ This creates an internal electric field(Ep) which reduces the overall field within the dielectric to E = Eo - Ep.
❂WHAT IS A DIELECTRIC CONSTANT?
➡ Dielectric constant (or relative permittivity) is the ratio of permittivity of the medium to the permittivity of free space/vacuum.
➡ The dielectric constant for vacuum is unity.
➡ A common example of a dielectric is the electrically insulating material between the metallic plates of a capacitor. The polarization of the dielectric by the applied electric field increases the capacitor's surface charge.
➡ Dielectric materials can be solids, liquids, or gases. In addition, a high vacuum can also be a useful, lossless dielectric even though its relative dielectric constant is only unity.
➡ Solid dielectrics are perhaps the most commonly used dielectrics in electrical engineering, and many solids are very good insulators.
➡ Some examples include porcelain, glass, and most plastics. Air, nitrogen and sulfur hexafluoride are the three most commonly used gaseous dielectrics.

definition = It is a quantity measuring the ability of a substance to store electrical energy in an electric field.
Dielectric constant is the property of an electrical insulating material (a dielectric) equal to the ratio of the capacitanceof a capacitor filled with the given material to the capacitance of an identical capacitor in a vacuum without the dielectric material.
The insertion of a dielectric between the plates of, say, a parallel-plate capacitor always increases its capacitance, or ability to store opposite charges on each plate, compared with this ability when the plates are separated by a vacuum.

Dielectric constant, property of an electrical insulating material (a dielectric) equal to the ratio of the capacitance of a capacitor filled with the given material to the capacitance of an identical capacitor in a vacuum without the dielectric material. ...
The dielectric constant is a number without dimensions. The term insulator is generally used to indicate electrical obstruction while the term dielectric is used to indicate the energy storing capacity of the material.
hope it works
