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 In terms of transformational grammar, the sentence can be analysed as being derived from *"si tuus parens haec tibi diceret" by raising "haec" and "tibi" to earlier in the sentence. A functionalist, on the other hand, would say that "haec" naturally comes first as the topic, then "si" in its normal place, then the unemphatic pronoun, without anything being moved. 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.
