Question
Suppose you have a three-phase generator that provides 120 Vạc per phase and works at a
frequency of 60 Hz, this generator can be connected in both delta and star. Also consider the
following 6 load impedances, which will be connected at the same time to the generator as
follows: ZA, ZB and Zc are connected in star, while Zp, Zg and Zp are connected in delta.
