If the load is connected to the generator thgrough an inductive line and the voltage at the load side is the same as the voltage at the terminals of the generator, which of the following must be true? O A. The reactive power is flowing from the generator to the load and from load to the generator at the same time. O B. The load is disconnected, and no power is delivered to the load. O C. The load has a poor power factor and it's absorbing too much reactive power. O D. None of the other choices are correct O E. The generator is unable to produce reactive power; therefore, the reactive power is flowing from the load to the generator.

For this kind a problem, how do you know how the voltage source is configured ( wye or delta). The problem start getting the phase current for phase 1 and 2 , but do we have to pretend that voltage source to delta load is connected like y-delta to convert the voltage to delta source? Or how does it work?
