Vedclass · Answer

(D) The dielectric constant $K$ (also known as relative permittivity $\epsilon_r$) is a measure of a material's ability to store electrical energy in an electric field.For an insulator (dielectric),the value of $K$ is always greater than or equal to $1$ $(K \ge 1)$.For a perfect conductor (metal),the dielectric constant is defined as $K = \infty$.Since the question asks for the value that an insulator cannot have,the correct answer is $\infty$,as this value is characteristic of conductors,not insulators.
