Hi there, my question above isn't to do with homework, just bothering me enough not to be able to concentrate on my readings.
I just want to know if there are instances in which 3phase power is used where High voltage DC would have been preferable? Where the real need would have been a straight line (a large amount of steady current) instead of a sine wave that doesn't drop to zero? Are motors the main and only reason that 3phase AC got invented?
(Sorry this is my first post and it is a desperate post because the question is really distracting me. I can describe my background a bit more later but right now have to finish studying within the hour)
