Answer to Question #301695 in Electricity and Magnetism for Chemistry

Question

A conductor is an extreme case of a dielectric, since if an electric field is applied to a conductor, charges are free to move within the conductor to set up “induced charges.” What is the dielectric constant of a perfect conductor? Is it K = 0, K S q or something in between? Explain your reasoning.

Answer 1

Answer

polarizability of a material is known as dielectric constant . it is The capability of a material to separate charges inside its body..

So, perfect conductor the electrical field E is always zero and k is defined as ratio of polarization density (P) by the electricl field (E).

so, for perfect conductor E=0

hence the dielectric constant must be infinite.
