Question:
A load consists of a large number N of identical resistors R (e.g. incandescent lights, toasters,. . . ) in parallel.Suppose they are powered by an AC generator with RMS voltage V. Compare the line losses if
(a) The load is connected to the generator by single-phase power
(b) The load is divided in three and each group is connected (in a wye configuration) to a single phase of three-phase power. Assume that all the conductors have resistance R0 and ignore line inductance. Finally, suppose the N resistors are connected in parallel to a DC generator. Compare the line losses if they are powered at the same level as the previous two cases.
