The dielectric strength is-xA0-the maximum-xA0-electric field that a pure material can withstand under ideal conditions without breaking down- For high voltage capacitors we use practically high dielectric strength-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- This fact is commonly used to increase the capacitance of a particular capacitor design-xA0-So for good capacitors we require high K and high X-
