Just as Hercules was escaping with the cattle and bringing it back to Eurystheus, a bull got loose at Rhegium and jumped into the sea.

Part of the Data center management glossary: An arc flash is an undesired electric discharge that travels through the air between conductors or from a conductor to a ground. The resulting explosion can cause fires and serious harm to equipment and people.
An electric arc between two nails. An electric arc or arc discharge is an electrical breakdown of a gas that produces an ongoing plasma discharge, resulting from a current through normally nonconductive media such as air.n electric arc differs from a glow discharge in that the current density is quite high, and the voltage drop within the arc is low; at the cathode, the current density can be as high as one megaampere per square centimeter. An electric arc has a non-linear relationship between current and voltage.
