Final answer:
The sequence network that includes the voltage/current sources is all sequence networks include voltage/current sources.
Step-by-step explanation:
The sequence network that includes the voltage/current sources is the All sequence networks include voltage/current sources. In electrical power systems, a sequence network is used to analyze the behavior of three-phase systems. The positive-sequence network represents the balanced conditions where all three phases have the same amplitude and phase sequence. The negative-sequence network represents the unbalanced conditions where one phase has reversed polarity. And the zero-sequence network represents the unbalanced conditions where all three phases have the same polarity.
