High $k$ and high $x$

Vedclass · Answer

(A) The dielectric constant $k$ (also denoted as $\epsilon_r$) determines the ability of a material to store electrical energy in an electric field. $A$ higher $k$ increases the capacitance of the capacitor $(C = k C_0)$.The dielectric strength $x$ is the maximum electric field that a material can withstand without undergoing electrical breakdown. $A$ higher $x$ allows the capacitor to operate at higher voltages without failing.Therefore,for an ideal capacitor,we require a material with both a high dielectric constant $(k)$ and high dielectric strength $(x)$.

If the dielectric constant and dielectric strength are represented by $k$ and $x$ respectively,what properties should a suitable material have to be used as a dielectric in a capacitor?
