WebA perfect conductor or perfect electric conductor (PEC) is an idealized material exhibiting infinite electrical conductivity or, equivalently, zero resistivity ( cf. perfect dielectric ). While perfect electrical conductors do not exist in nature, the concept is a useful model when electrical resistance is negligible compared to other effects. WebWhat Is Permittivity? Permittivity is the property of every material, which measures the opposition offered against the formation of an electric field. It is represented by the Greek …
