The Dielectric Constant
Every material has a dielectric constant κ. This is the ratio of the field without the dielectric (E o) to the net field (E) with the dielectric: κ = E o /E E is always less than or equal to E o, so the dielectric constant is greater than or equal to 1. The larger the dielectric constant, the more charge can be stored.
