Explain about the Dielectric Breakdown
Dielectric Breakdown of a dielectric material is because of the excitation of electrons into the conduction band across energy gap under conditions of excessive voltage, resulting in an avalanche of conducting electrons and consequent physical breakdown.
There are two conditionfor foramtion of anions a) High Electron affinity b) Small size Less charge of an atoms form anion more simply
