U is the electric potential energy (in J) stored in the capacitor’s electric field. This energy stored in the capacitor’s electric field becomes essential for powering various applications, from smartphones to electric cars (EVs). Dielectrics are materials with very high electrical resistivity, making them excellent insulators.
The cavity is usually vacuum or contains air with the dielectric constant of ε 0 . The relative permittivity of the capacitors’ dielectric is ε r . As described above, the cavity is usually very tiny. Thus, only the electric field around the crack will be enhanced. The electric field far from the cavity remains the same, which is as follow:
As far as the field inside the capacitor is concerned, there tends to be no normal component of E. In the opposite extreme, where the region to the right has a high permittivity compared to that between the capacitor plates, the electric field inside the capacitor tends to approach the interface normally.
As is clear by taking the limit a /b 0 in (36), the field inside the capacitor tends to be uniform right up to the edge of the capacitor. The dielectric effectively ducts the electric field. As far as the field inside the capacitor is concerned, there tends to be no normal component of E.
The greater k value means the enhancement is more remarkable and the electric field is higher near the cavity. As described above, the difference between the dielectric constant of a capacitor’s dielectric and that of cavity is the one of the reasons for electric field enhancement. For the cavity, the dielectric constant is constantly e0.
A dielectric can be placed between the plates of a capacitor to increase its capacitance. The dielectric strength E m is the maximum electric field magnitude the dielectric can withstand without breaking down and conducting. The dielectric constant K has no unit and is greater than or equal to one (K ≥ 1).
