What is breakdown voltage and dielectric strength?
The breakdown voltage for a substance or dielectric is the minimum voltage or potential difference between two ends of a substance required to cause an electric breakdown. The dielectric strength is given by the potential gradient necessary to cause breakdown of an insulator or substance.
What is the other name for dielectric strength?
relative permittivity
While the dielectric strength characterises the material’s insulating quality, the dielectric constant is a dimensionless mathematical ratio of the material permittivity to the permittivity of vacuum, which gives it the alternative name “relative permittivity”.
What is the other name of breakdown voltage?
Within rarefied gases found in certain types of lamps, breakdown voltage is also sometimes called the striking voltage. The breakdown voltage of a material is not a definite value because it is a form of failure and there is a statistical probability whether the material will fail at a given voltage.
Is dielectric strength the same as dielectric constant?
The key difference between dielectric constant and dielectric strength is that dielectric constant is the ratio between the capacitance of an insulating material and the capacitance of vacuum whereas dielectric strength is the electrical strength of an insulating material.

What do you understand by dielectric breakdown?
Dielectric breakdown is the failure of an insulating material to prevent the flow of current under an applied electrical stress. The breakdown voltage is the voltage at which the failure occurs, and the material is no longer electrically insulating.
What is meant by dielectric strength?
Dielectric strength is defined as the electrical strength of an insulting material. In a sufficiently strong electric field the insulating properties of an insulator breaks down allowing flow of charge. Dielectric strength is measured as the maximum voltage required to produce a dielectric breakdown through a material.
What is meant by dielectric and dielectric strength?
Dielectric strength is defined as the electrical strength of an insulting material. Dielectric strength is measured as the maximum voltage required to produce a dielectric breakdown through a material. It is expressed as Volts per unit thickness.
