A zero‐current electrometer method and its application to charge‐decay measurements

摘要

A zero‐current electrometer method is presented. It allows static charge measurements with a precision comparable to that of classical electrometers and current measurements without any current flow in the external circuit. The advantages of this technique are pointed out. The apparatus is used in the investigation of a new charge‐decay process due to the interaction of the electret with molecules of a solvent. The observed effects are interpreted in terms of hopping conduction stimulated by chain motion.
