Dielectric strength vs resistance
Web123 rows · Dielectric Strength reflects the electric strength of insulating materials at various power frequencies. Or it can be defined as the measure of dielectric breakdown … WebDifferences in dielectric strength values may result when comparing 1/4 in and 2 in diameter brass electrodes. Because of the larger film area between the electrodes, the potential for lower dielectric strength values is greater with 2-in electrodes. Figure 1.
