Abstract
Apparatus and methods for creating a fault such as a varying resistance fault causing static are disclosed. Devices according to the invention include a housing having an entrance face and defining an interior region, a quantity of granular electrically conductive material contained within the interior region, and a pair of electrical conductors extending through the entrance face of the housing, each conductor having a first portion that extends into the interior region of the device. Each of the first portions includes a distal portion that is in electrical contact with the granular conductive material, and the quantity of granular material is such that the granular material provides an intermittent electrical connection between the distal portions.
