Abstract
The internal charge distribution of the carnauba wax electret has been determined by a sectioning method: After polarization and cooling samples are cut into sections of different thickness. These are reheated and the ensuing discharge currents are measured. The total released charge, as determined by numerical integration of the corresponding current—time curve, gives the polarization of each section. A macroscopic space charge polarization would give charge values which, with decreasing thickness of sections, go to zero; a uniform volume polarization would give values which are independent of thickness. Measurements gave constant values and therefore prove the existence of a uniform volume polarization of the electret.
