I heard the US moved to 120V cos the electric chair was more efficient at that voltage.
y is it AC? y not DC? does the same reason holds good for this?
Trains too had a different space between their wheels a long time ago and when the track spacing was changed the old trains didn't fit.
Accurate but incomplete.AC is preferable over DC due to the IR drop along transmition lines. For long lines very high voltage -low current, transformed at destinatio to operating voltage. Difference in AC voltage and frequency purely due to local developement.
