At the initial stage of the same breaking current post zero, the vacuum dielectric strength is higher than that of. In theory, vacuum can be considered as a medium of constant unity. (recall that \(e=v/d\) for a parallel plate capacitor.) also shown in this table are maximum electric field strengths in v/m, called dielectric strengths.

The dielectric constant of vacuum or air is ∼1, whereas the constants for some commonly used dielectric materials are ∼2 for polypropylene, ∼3 for polyester (mylar™), ∼7 for mica, ∼8 for aluminum oxide, and ∼26 for tantalum pentoxide. As indicated by e r = 1.00000 for a vacuum, all values are relative to a vacuum.

A dielectric can be a vaccum, a glass, mica, bakelite, plexiglass, paper etc., so what dielectric does is reduces the overall electric field say when inserted in a capacitor, this happens as because of polarisation in dielectric material, charges are induced in dielectric which creates an opposite electric field resulting in lowering of electric field generally positive charge is. Dielectrics in capacitors can be vacuum, gaseous (such as air), liquid (such as mineral oil), solid (such as glass, titanium oxide, or sodium) or a combination of liquid and solid (such as oil impregnated paper or mica).

When vacuum is used as a dielectric, the capacitance is given by `c_{0}=\varepsilon_{0}\left(\frac{a}{d}\right)` where `\varepsilon_{0}` is the permittivity of vacuum. Asking where that comes from is asking a much deeper question about the fundamentals of the physical world and has no concrete answer as of yet. Vacuum or free space can be considered as a dielectric.
