Answer / sam

A/C cannot be stored as other guys have answered,

D.c cannot be transmitted because the area of conductor
required is more to transmit DC that increases the cost.
while to transmit 3phase power is much less (As per the
formulas).

would the same effect be achieved by reversing the connection to one winding of the induction motor 3-phase?
