Brush discharge plastics. The ability of an electrical discharge to cause an explosion in flammable atmospheres is measured by the "effective energy" of the discharge. The effective energy of brush discharges is 10-20 mJ, much larger than that of corona discharges 0.1 mJ. Therefore, brush discharges are considered an explosion hazard, while corona discharges are not. Brush discharges can occur from charged insulating plastics (for example polythene) to a conductor. Brush discharge A brush discharge is an electrical disruptive discharge similar to a corona discharge that takes place at an electrode with a high voltage applied to it, embedded in a nonconducting
Latin word order Latin word order The word order of classical Latin is relatively free. Subject, Object, and Verb can come in any order; adjectives and possessives can go before or after their noun, and so on. A commonly found feature of Latin is hyperbaton, in which a phrase is split up by other words, e.g. "Sextus est Tarquinius" "it is Sextus Tarquinius". A complicating factor in Latin word order is that there are variations between the style of different authors, and also between different genres of writing; in Caesar's historical writing the verb is much more likely to come at the end
