Question

In the figure shown below, what will be the line voltage? (a) VBR (b) VBN (c) VRN (d) VYN The question was posed to me in an online interview. My query is from Inter Connection of Three-Phase Sources and Loads in chapter Polyphase Circuits of Network Theory Select the correct answer from above options network theory questions and answers, network theory questions pdf, network theory question bank, network theory gate questions and answers pdf, mcq on network theory pdf, gate network theory questions and solutions, network theory mcq Test , ies network theory questions, Network theory Questions for GATE EC Exam, Network Theory MCQ (Multiple Choice Questions)

Answer 1

Right answer is (a) VBR For explanation I would say: The star connected system formed will supply equal line voltages displaced 120^ from one another and acting simultaneously in the cicruit like three independent single phase sources in the same frame of a three phase alternator. Line voltage = VBR. And VRN , VYN and VBN are not line voltages.
