The IEC 479-1 report specifies time/current zones of the effects of alternating currents
(15 to 100 Hz) and of direct currents passing along the left hand to both feet path.
The War of Currents more briefly was basically the conflict between superiority of alternating current
versus direct current.
For instance, one of the more heated arguments of the day was between Edison and his rival George Westinghouse, who wanted to use alternating currents
in his own power plants rather than the direct current favored by the "Wizard of Menlo Park." The Edison camp mounted a propaganda campaign against Westinghouse very similar to the scaremongering to which Edison had himself been subjected by the gas-light companies earlier in his career.
The theme of the Biennale, curated by Okwui Enwezor and an international team and featuring some 160 artists from 63 countries, was "Trade Routes: History and Geography," and some of the subthemes in the show, such as "Alternating Currents
" and "Transversions," reveal the show's preoccupation with hybridity, metissage, and globalization.
electric power industry launched a nationwide survey in late 1990 to map fields associated with the alternating currents
that power America's homes.
