At breakdown, the electric field frees bound electrons. If the applied electric field is sufficiently high, free electrons from background radiation may be accelerated to velocities that can liberate additional electrons by collisions with neutral atoms or molecules, in a process known as avalanche breakdown . Ver mais In physics, the term dielectric strength has the following meanings: • for a pure electrically insulating material, the maximum electric field that the material can withstand under ideal conditions without undergoing Ver mais The field strength at which break down occurs depends on the respective geometries of the dielectric (insulator) and the electrodes with which the electric field is applied, as well as the rate of increase of the applied electric field. Because dielectric materials … Ver mais • Breakdown voltage • Relative permittivity • Rotational Brownian motion Ver mais Electric current is a flow of electrically charged particles in a material caused by an electric field.
