- A dielectric, is an insulating material such as mineral oil or plastic, and is characterized by a numerical factor κ, called the dielectric constant of the material.
- Some dielectrics, such as strontium titanate, can increase the capacitance by more than two orders of magnitude.
- The introduction of a dielectric also limits the potential difference that can be applied between the plates to a certain value Vmax, called the breakdown potential.
- Every dielectric material has a characteristic dielectric strength, which is the maximum value of the electric field that it can tolerate without breakdown.
