Why are we using Alternationg Current today? There are a few reason although mainly it was due to the technology of the late 1800's and early 1900's. Nikola Tesla being one of the leading scientists for Alternating Current, created a way to run engines and also convert AC Volts and Amps. He came up with this while he was supposedly in a park in Budhapest. He sat down and drew out the basic diagram of a motor run by a magnetic flux. This supplied Alternating Current with a serious advantage. The loss of power per mile tramitted is proportional to that of the Current squared. If Tesla was able to convert the Amps to Volts, then they could easily have a place where the power is upped to a high amount of volts for transfer, and then lower the volts at the other end to a more acceptable value. This however had not been developed for DC, which was supported by the renowned brain-box Einstein.  Unfortunately Einstein attacked AC by trying to prove that a high voltage was seriously deadly. As it turns out this however true was not proper, amps can kill much more efficiently than volts. Unfortuantely for the proprietors of DC they were forced to supply their power at a high amperage and a low voltage, which specifically has a high loss of power over shorter distances. This was one of the main clinching facts for the use of AC over DC.
