In earlier articles, I have explained the-

Here, we are going to study the major difference between an insulator and a dielectric.

Insulator vs Dielectric [in Tabular Form]

#Content Insulator Dielectric
01[Definition] What is an insulator & a Dielectric? The material which does not allow to flow of electric current in an applied electric field is called as an ‘Insulator’.The material which allows to flow of electric current in an applied electric field is called as a ‘Dielectric’.
02Function of insulator & DielectricThe insulator does not store the electric charge.The dielectric stores the electric charge.
03PolarizationThe insulator can not be polarized under the influence of the electric field. The dielectrics can be easily polarized under the influence of the electric field.
04Molecular bondIt has a covalent bond.It has weakly bond as compared to the insulator.
05Property of conductivityThe insulator has low conductivity. The dielectric has high conductivity.
06Property of ResistivityIt has high resistive power. It has low resistive power.
07Can any insulator be a dielectric?All insulators are not worked as dielectrics.But, all dielectrics are worked as insulators.
08Protection The insulator does not require protection due to the absence of conducting material.The dielectric requires protection due to the presence of conducting material.
09Dielectric constant The insulator has a low dielectric constant.The dielectric has a high dielectric constant.
10UsedIt is mainly used for limiting current to the desired path.It is used for flowing electric current to the desired path.
11Insulating & Dielectric materialsThe insulator finds in the form of glass, cotton, plastic, mica, rubber, etc.The dielectric media finds in the form of dry air, vacuum, distilled water, etc.
12Application of insulator & dielectricIt is used in transmission and distribution systems, and other conducting wires. It is used in the battery, capacitor, power cables, mineral oil (especially in transformer tank), dielectric resonator oscillator (DRO), etc.

These are the basic points to distinguish between dielectric and conductor. If you have any queries regarding the insulator or dielectric, please comment below.
