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 Ea
Choose the correct answer
- A. 4.78 ohm B. 1.02 ohm C. 1.3 ohm D. 1.72 ohm E. 2.53 ohm
- A. 137.12 volt B. 134.67 volt C. 133.92 volt D. 134.17 volt E. 134.89 volt
