GENERAL KNOWLEDGE

Detailed explanation-1: -(Dielectric strength is the maximum electric field a material can tolerate without breakdown, i.e., without starting to conduct electricity through partial ionisation.) For safety, we should like the field never to exceed, say 10% of the dielectric strength.

Detailed explanation-2: -EXPLANATION: The maximum strength of the electric field that dielectric material can withstand out the breakdown of its insulating property is called dielectric strength.

Detailed explanation-3: -The presence of the dielectric decreases the electric field produced by a given charge density. The factor k by which the effective field is decreased by the polarization of the dielectric is called the dielectric constant of the material.
