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 ...
A rounded terminal minimizes the electric field around it, allowing greater potentials to be achieved without ionization of the air, or other dielectric gas, surrounding it. Since a Van de Graaff generator can supply the same small current at almost any level of electrical potential, it is an example of a nearly ideal current source.
The Kelvin water dropper, invented by Scottish scientist William Thomson (Lord Kelvin) in 1867, [1] is a type of electrostatic generator. Kelvin referred to the device as his water-dropping condenser. The apparatus is variously called the Kelvin hydroelectric generator, the Kelvin electrostatic generator, or Lord Kelvin's thunderstorm.
The Elekiter relied on the various Western experiments with static electricity during the 18th century, which depended on the discovery that electricity could be generated through friction, and on the invention of the Leyden jar in the 1740s, as a convenient means to store static electricity in rather large quantities.

The National Flag of Canada (French: Drapeau national du Canada), [1] often referred to simply as the Canadian flag, consists of a red field with a white square at its centre in the ratio of 1∶2∶1, in which is featured one stylized, red, 11-pointed maple leaf charged in the centre. [2]
