The War of Currents more briefly was basically the conflict between superiority of alternating current versus direct current.
He spread misinformation saying that alternating current was more dangerous even going so far as to publicly electrocute stray animals using alternating current to prove his point.
electric power industry launched a nationwide survey in late 1990 to map fields associated with the alternating currents that power America's homes.
However, this analogy is somewhat like comparing apples and oranges, since Earth's magnetic field is static, while those due to alternating current oscillate at one or more characteristic frequencies.
This DC conversion is necessary because the alternating currents
on either side of the border are not synchronous with one another.
