1.	27. Define dielectric strength and relative
Answer» 1)Relative permittivityis the factor by which the electric field between the charges is decreasedrelativeto vacuum. Likewise,relative permittivityis the ratio of the capacitance of a capacitor using that material as adielectric, compared with a similar capacitor that has vacuum as itsdielectric. 2)In physics, the termdielectric strengthhas the followingmeanings: Of an insulating material, the maximum electric field that a pure material canwithstandunder ideal conditions without breaking down (i.e., without experiencing failure of its insulating properties)
