(AC) alternating current

*In 1887 in his Manhattan lab Tesla built the first brushless alternating current generator

* alternating and direct current were locked in a energy war. But due to its more effective high energy nature AC became the standard energy type

* unlike dc, ac is of higher voltage and can more effectively be transferred long distances without losing energy

*dc current impacts us because it is still the current used to power modern society
