Abstract
The magnitude of the electrostatic charge density on an insulating belt of photographic film increases as the belt passes repeatedly over a set of grounded metal rollers. The charge density q asymptotically approaches an equilibrium value qe according to the relation q = qe (1 − e−n/τ), where n is the number of roller passages and τ is an arbitrary constant. An equivalent circuit which describes this behavior is presented. The circuit elements are an electromotive force, a contact resistance, a leakage resistance, and a capacitance between the belt and the roller. The physical equivalents of these elements and the possibility of their measurement are discussed.This publication has 6 references indexed in Scilit:
