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
Demise of the Crown Demise of the Crown The demise of the Crown is the legal term for the end of a reign by a king, queen regnant, or emperor, whether by death or abdication. The term was coined in English law to signify the immediate transfer (Law French "demise", "sending down [the line of succession]", from Latin "demiss"-[gender ending], the perfect participle of "demittere", having the same meaning), of sovereignty and royal prerogatives to the late king or queen's successor without interregnum.
