ABSTRACT
The electric strength of solid dielectrics depends on many extraneous factors, already discussed in connection with the breakdown of liquids, unless extreme precautions are taken. The measured electric strength of apparently similar specimens of the same material varies over a wide range. Factors that greatly affect the measurements are
• High field concentrations at the edges of the electrodes. • Thickness and homogeneity of different samples even from the same material. To miti-
gate this problem, single crystals of solids with simpler molecular structure have been employed for studies.
