Talk:Relative permittivity/Comments

In the 'Practical relevance', the line "If a material with a high dielectric constant is placed in an electric field, the magnitude of that field will be measurably reduced within the volume of the dielectric." is confusing because a material with high permittivity (and thus dielectric constant) should increase the strength of the electric field between two metal plates and thus allow it to hold more charge. This contrasts to materials with smaller dielectric constants which reduce the electric fields. This is used in PCBs to insulate signal carrying conductors from each other. http://www.siliconfareast.com/dielectric-constant.htm (At the bottom). The section should be reworded to properly distinguish between the two applications given its dielectric constant value.
