(Wikipedia excerpt:…”…Electrostatics/ally (E) is a branch of physics that studies electric charges at rest ( (E) electricity). Since classical times, it has been known that some materials, such as amber, attract lightweight particles after rubbing. The Greek word for amber, ἤλεκτρον (ḗlektron), was thus the source of the word ‘electricity’. (E) phenomena arise from the forces that electric charges exert on each other. Such forces are described by Coulomb’s law. Even though (E) induced forces seem to be rather weak, some (E) forces are relatively large. The force between an electron and a proton, which together make up a hydrogen atom, is about 36 orders of magnitude stronger than the gravitational force acting between them.
There are many examples of (E) phenomena, from those as simple as the attraction of plastic wrap to one’s hand after it is removed from a package, to the apparently spontaneous explosion of grain silos, the damage of electronic components during manufacturing, and photocopier & laser printer operation. (E) involves the buildup of charge on the surface of objects due to contact with other surfaces. Although charge exchange happens whenever any two surfaces contact and separate, the effects of charge exchange are usually noticed only when at least one of the surfaces has a high resistance to electrical flow, because the charges that transfer are trapped there for a long enough time for their effects to be observed.”)
