In earlier articles, I have explained the-
- difference between insulator and conductor with specifications
- different types of insulator with specification, properties and uses
Here, we are going to study the major difference between an insulator and a dielectric.
Insulator vs Dielectric [in Tabular Form]
|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’.|
|02||Function of insulator & Dielectric||The insulator does not store the electric charge.||The dielectric stores the electric charge.|
|03||Polarization||The 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.|
|04||Molecular bond||It has a covalent bond.||It has weakly bond as compared to the insulator.|
|05||Property of conductivity||The insulator has low conductivity.||The dielectric has high conductivity.|
|06||Property of Resistivity||It has high resistive power.||It has low resistive power.|
|07||Can any insulator be a dielectric?||All insulators are not worked as dielectrics.||But, all dielectrics are worked as insulators.|
|08||Protection||The insulator does not require protection due to the absence of conducting material.||The dielectric requires protection due to the presence of conducting material.|
|09||Dielectric constant||The insulator has a low dielectric constant.||The dielectric has a high dielectric constant.|
|10||Used||It is mainly used for limiting current to the desired path.||It is used for flowing electric current to the desired path.|
|11||Insulating & Dielectric materials||The 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.|
|12||Application of insulator & dielectric||It 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.

Thanks for Reading!
I have completed master in Electrical Power System. I work and write technical tutorials on the PLC, MATLAB programming, and Electrical on DipsLab.com portal.
Sharing my knowledge on this blog makes me happy. And sometimes I delve in Python programming.
