A comb-shaped metal electrode with sharp points (2 and 7 in the diagram), is positioned near each roller. The upper comb (2) is connected to the sphere, and the lower one (7) to ground. When a motor is used to drive the belt, the triboelectric effect causes the transfer of electrons from the dissimilar materials of the belt and the two rollers ...
Experiments involving triboelectricity and static electricity occurred before the discovery of the electron. The name ēlektron (ἤλεκτρον) is Greek for amber , [ 10 ] [ 11 ] which is connected to the recording of electrostatic charging by Thales of Miletus around 585 BCE, [ 12 ] and possibly others even earlier.
An electrostatic generator, or electrostatic machine, is an electrical generator that produces static electricity, or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon , without a ...
Franklin's electrostatic machine on display at the Franklin Institute. Franklin's electrostatic machine is a high-voltage static electricity-generating device used by Benjamin Franklin in the mid-18th century for research into electrical phenomena.
Electrostatic generator, machines that create static electricity. Electrostatic induction, separation of charges due to electric fields. Permittivity and relative permittivity, the electric polarizability of materials. Quantization of charge, the charge units carried by electrons or protons.
Armstrong Hydroelectric Machine. The Armstrong effect is the physical process by which static electricity is produced by the friction of a fluid. It was first discovered in 1840 when an electrical spark resulted from water droplets being swept out by escaping steam from a boiler.
Other early studies noting the interaction of static electricity with water and reported in the English language include: Francis Hauksbee "Physico-Mechanical Experiments on Various Subjects". (1719) William Watson, "Experiments and Observations Tending To Illustrate The Nature and Properties of Electricity". (MDCCXLVI) (1741)
Corbett's electrostatic machine is a static electricity generating device that was made by the Shaker physician Thomas Corbett in 1810. Intended to treat rheumatism , [ 1 ] the device built up a static charge and stored it in a Leyden jar , an early type of capacitor .
