Question

what is dielectric break down?summaries the various factors contributing to down in dielectrics.

Answer 1

An electrical breakdown in adielectric refers to an abrupt drop of resistance, i.e., increasing conductivity. It is caused by the fact that charge carriers gain sufficient energy to ionize parts of the lattice of the material and thus create more charge carriers.
