insulators will not allow current due to large energy band gap,but the dielectric have less energy band gap so the dielectric allow current flow.energy band gap is nothing but the energy required for an electron to cross the energy barrier in order to flow (current)

Difference Between Insulator And Dielectric
2017-01-16 04:01:29 · answer #2 · answered by ? 4 · 0⤊ 0⤋
A true insulator does not repsond to an electric field. A dielectric does, with a redistribution of charge. Size of band gap has aboslutely nothing to do with it - for instance, gases and liquids can be dielectric but, lacking a lattice, cannot have a band gap.
A dielectric can also be a conductor provided it polarizes under an electric field.

as per technical uasge they both give the same function.
the main difference between insulator and dielectric is:
when we place a dielectric material between capacitor plates,then the process of polrization is developed.polarization is nothing but separating both+ve and -ve charges.and it leads to constitution of dipoles.and we can have more capacitance.
and in the case of insulator thi will not happen.

the main suitable distinction between the two, different than a conductor conducts the two warmth and electrical energy the place is an insulator does not, is the style of electrons located interior the outer shell. A conductor has the two a million, 3, or 5 electrons interior the outer shell. the two copper and silver has in undemanding terms a million electron interior the outer shell. it is why copper is utilized in homestead wiring. A insulator frequently has the two 4 or 8 electrons interior the outer shell. Carbon, which has 4 electrons interior the outer shell, is a reasonably reliable insulator. it is why carbon is used to make resistors.

Insulator is more generic, used for both electricity and heat, while dielectric is used for electricity only.

getdetails about energy gap
http://en.wikipedia.org/wiki/Band_gap
there u find answer
also insulator need more energy to break down and pass current
than dielectrics

the answer is in ur question itself.insulator is for both heat and electricity and the term does not tell us about the alignment of electric dipoles,but the term dilectric tells something about that..

No. Both have the same meaning.
