(Greek: a suffix; pertaining to; of the nature of, like; in chemistry, it denotes a higher valence of the element than is expressed by -ous)
2. In modern music, denoting the scale which in any key proceeds by the notes proper to that key without chromatic alteration; hence, applied to melodies and harmonies constructed from such a scale.
2. Pertaining to a substance or medium that can sustain a static electric field within it.
3. Relating to something that is a poor conductor of electricity, but an efficient supporter of electrostatic fields: Dielectric conditions can support an electrostatic field while dissipating minimal energy in the form of heat; frequently used in capacitors.
4. A type of insulator which becomes polarized when it comes in contact with an electrical field: The dielectric material can easily support an electrostatic field even though it is not a conductor of electricity.
Such dielectric materials are used in many places; such as, in capacitors and radios, as well as transmission lines for radio frequency and it can be used to store energy too, if it is configured properly.
Most of these dielectric materials are solid in nature, but some fluids and gasses also exhibit dielectric properties; such as gas is dry air, while examples of solid dielectric materials include mica, ceramic, plastics and glass and even distilled water is considered to be a dielectric liquid.
