Re: why sine waves in power lines and why not square wave!


"Shashi"

Why are we using sine wave A.C in power transmission lines?


** Cos that is what rotating generators / alternators have produced since
decades.


Why shouldn't we use Square wave AC instead of Sine?


** Cos the ratio of RMS to peak value being 0.71 has become so important.

Square wave power that would operate lamps normally would not operate 90%
of electronics.
