a substance or medium that can sustain a static electric field within it
2.
a substance or body of very low electrical conductivity; insulator
adjective
3.
of, concerned with, or having the properties of a dielectric
Derived forms
dielectrically (ˌdieˈlectrically)
adverb
Word origin
from dia- + electric
dielectric in American English
(ˌdaɪɪˈlɛktrɪk)
noun
1.
a material, as rubber, glass, etc., or a medium, as a vacuum, gas, etc., that does not conduct electricity but can sustain an electric field: dielectrics are used in capacitors, between adjacent wires in a cable, etc.
adjective
2.
having the properties or function of a dielectric
Word origin
dia- + electric: so called because it permits the passage of the lines of force of an electrostaticfield but does not conduct the current
