Corona discharge 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 electrically charged. Spontaneous corona discharges occur naturally in high-voltage systems unless care is taken to limit the electric field strength. A corona will occur when the strength of the electric field (potential gradient) around a conductor is high enough to form a conductive region, but not high enough to cause electrical breakdown or arcing to nearby objects. It is often seen as a bluish (or other color) glow in the air adjacent to pointed metal
Latin influence in English text in Latin, the prevalent Medieval lingua franca of Europe. However, when monks occasionally wrote in the vernacular, Latin words were translated by finding suitable Old English equivalents. Often, a Germanic word was adopted and given a new shade of meaning in the process. Such was the case with Old English "gōdspell" ("gospel") for Latin "evangelium". Previously, the Old English word simply meant "good news," but its meaning was extended in Old English to fit a religious context.
