1.	Phase sequence depends on the _________________(a) field(b) rotation of the field(c) armature(d) rotation of the armatureI have been asked this question by my college professor while I was bunking the class.I'm obligated to ask this question of Polyphase System topic in division Polyphase Circuits of Network Theory
Answer» CORRECT answer is (b) rotation of the FIELD Easiest explanation: The SEQUENCE of voltages in the three phases UNDERGO changes ONE after the other abd this is called phase sequence. Phase sequence depends on the rotation of the field not on rotation of armature or on field or on armature.
