the dielectric plate is first rubbed with a cloth to create a static charge through friction. This is another example of the triboelectric effect, as also used in the Van de Graaff generator.

Learning the 'effective' notions of static and sliding friction ... We might naively expect rough surfaces to show greater friction, for example, yet it is sometimes higher between perfectly ...

Rate-and-state laws predict that there is no static friction coefficient and that shear movement occurs under all shear ...
