Hi Guys,
I was discussing with a friend why AC is used for power transmission over DC and apart from the fact that power electronics for DC voltage stepping up/down was high cost at the time the "grid" was established we did not know any other reasons. Does AC have higher losses than DC, if so why? also does the stray inductance/capacitance in the transmission lines adjust the power factor of the voltage/current on the AC line?
Hope you can help
