1.	Figure below represents three phases of an alternator. The phase voltage for the star connection among the options given below is?(a) VRY(b) VRN(c) VYB(d) VBRThe question was posed to me during an online exam.My enquiry is from Inter Connection of Three-Phase Sources and Loads in division Polyphase Circuits of Network Theory
Answer» Correct option is (b) VRN The BEST I can explain: If the neutral WIRE is not available for external CONNECTION, the system is called a three phase,three wire STAR CONNECTED system. Phase voltage = VRN. And VRY, VYB and VBR are not phase voltages.
