The DC armature resistance of Y-connected alternator measured across its two terminals is 0.6 Ω. The per phase resistance is: Correct answer: 2. 0.3 Ω Explanation: The DC resistance measured across any two terminals of Y connected alterantor is that of two phase. Therefore the per phase DC armature resistance is half of measured value. … Read more
