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 ...

Discover the fascinating world of static electricity through simple balloon experiments. You'll learn how static charges build up through friction, how they attract or repel objects, and see everyday ...
