WHAT IS DI- ELECTRIC CONSTANT?

Expert Answer:


A metal is not a good dielectric. A vacuum is a decent dielectric. There are much better dielectrics than a vacuum. A high dielectric constant, k, means the material exhibits good dielectric behaviour. A vacuum has k = 1, better dielectrics have k > 1

The permittivity of a metal is negative. (for a perfect conductor it is -Inf)
