Interview Question in Dielectrics

Interview Question :: Is there any difference between dieletric and an insulator

for the sake of simplicity we often call a dielectric as an insulator.Both do not have mobile charged particles.still the terms cannot be used as such.kindly answer my query.

RE: Is there any difference between dieletric and an insulator?
A dielectric is a substance which contains electric dipoles in its inner structure arranged in a random way, remember the electric dipole is formed by a pair of charges and not a single charge so having dipoles doesnt mean free charged particles but there can be mobile dipoles. On the other hand insulator is a term used generally for those materials which do not conduct heat or electricity. An organic compound has dipoles( due to inductive effect) so its dielectric but its an insulator( as it doesnt conduct electricity) also, on the other hand, an ionic compound also has dipoles but its solution is a good conductor and hence its not an insulator.

RE: Is there any difference between dieletric and an insulator?
yes, there is a difference between dielectric and insulator. insulator in general don't transfer heat & electricity through, eg. plastic. but if u consider dielectric then it can transfer heat through it, eg. consider amonia gas. it is a dielectric medium and by convection it can carry heat through it. the dielectric has electric dipoles which can align themselves, when an electric field is applied across them along the direction of field.so generally these materials aren't rigid solids. where as the insulators are made in form of rigid solids.
