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.
Summary: Dielectric breakdown is the formation of conducting paths through an insulating material in the presence of an extremely strong electric field.High-voltage transformers contain oil as their insulating dielectric.ummary: Dielectric breakdown is the formation of conducting paths through an insulating material in the presence of an extremely strong electric field.
