Charge Growth Equation for Belts of Insulating Materials Passing over Grounded Rollers

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