Iron sulfide is a chemical compound (different from a mixture of Iron and Sulfur, show by its different physical and chemical properties). It is made of iron and sulfide ions.
A dielectric material (dielectric for short) is an electrical insulator that can be polarized by an applied electric field. dielectric resonator oscillator (DRO) is an electronic component that exhibits resonance of the polarization response for a narrow range of frequencies, generally in the microwave band. It consists of a puck of ceramic that has a large dielectric constant and a low dissipation factor.
Most of the materials used in electrical or electronics as insulators have a dielectric strength or a dielectric constant value. The higher the dielectric stregnth of a material the greater the chance that it will survive a higher voltage and current level in operation.ating Newest Oldest. Best Answer: A dielectric is a medium that does not usually conduct electricity well. If the voltage across such a dielectric medium is sufficiently large, dielectric breakdown can occur.
