Corona discharge with a discharge current of a few hundred microamperes can blow out a small candle flame within about 1 cm of a discharge point. A pinwheel, with radial metal spokes and pointed tips bent to point along the circumference of a circle, can be made to rotate if energized by a corona discharge; the rotation is due to differential electric attraction between the metal spokes and the space charge shield region that surrounds the tips. Corona discharge A corona discharge is an electrical discharge brought on by the ionization of a fluid such as air surrounding a conductor that is
Latin word order "nobody has yet succeeded in unifying the insights of all the different scholarly approaches to the fascinating and peculiar problem of Latin word order". In his view an approach which combines the various schools of thought on Latin word order "may succeed in finding a more satisfactory solution".
