War of the currents - Wikipedia The war of the currents, sometimes called battle of the currents, was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s.It grew out of two lighting systems developed in the late 1870s and early 1880s; arc lamp street lighting running on high-voltage alternating current (AC), and large-scale low-voltage direct AC vs DC: why does it matter? - ABB Group Then along came Nikola Tesla, thefather of AC motors and generators. Ifyou make AC at any voltage, it can be transformed through use of the highly efficient transformer to any other voltage. Stepping up the voltage has the effect of stepping down the current for the same power transfer. Why does DC vs … Difference Between AC and DC Motors | Precision Electric ... Difference Between AC and DC Motors. Commonly ran by an AC variable frequency drive, an AC electric motor operates by applying alternating current (AC) power to the electric motor. An AC electric motor consists of several parts but the main parts are the stator and rotor. Fan (machine) - Wikipedia
