Abstract

A model of an electret in the form of a plane-parallel plate with ohmic currents flowing over its surface and in its volume is considered. Assuming that the residual polarization decreases exponentially, the differential equation for the electret potential difference is written and solved. This potential difference is expressed as a series with a set of relaxation times determined by the volume and surface conductivities and also by the electret diameter and thickness.
