A parallel excitation DC generator
A parallel excitation DC generator has an excitation field resistance of 50ohm. When the generator serves a 3kw load at 110volt, the internal induced voltage is 160volt. If the load is reduced to 1/4 from before, with a generator output voltage of 120 volts, find the value of the inductor drum resistance(Ra) and EaChoose the correct answer1. A. 4.78 ohm B. 1.02 ohm C. 1.3 ohm D. 1.72 ohm E. 2.53 ohm2. A. 137.12 volt B. 134.67 volt C. 133.92 volt D. 134.17 volt E. 134.89 volt
