Answer Posted / uzair bin khalid

The difference between dielectric and insulator lies in its
field of application. Dielectrics are used to store the
electric charges, while insulators are used to block the
flow of electric charges (they more or less act like a
wall). While all dielectrics are insulators (they don't
allow the flow of electric charges through them) all
insulators aren't dielectric because they can't store
charges unlike dielectrics.
