3.The shunt field of a dc compound motor has a resistance of 200 ohms, a series field resistance of.0018 ohms and an armature resistance of 0.5 ohms. If the motor develops a back emf of 200 V at a full load current of 50A, and a rotational loss of 400 w, determine: a. The field currents b. The supply voltage

#11 Step Up Transformer A transformer primary coil has 2,300 windings, while the sec- ondary coil has 12,400 windings. If the primary coil is operated at a RMS voltage of 10.0 V, what is the RMS voltage in the secondary coil? A. 1.86 V В. 24.1 V С. 53.9 V D. 120 V

4. A businessman from Zimbabwe buys a transformer so that he can use his own electric appliances on a trip to the United States. The input coil has 60 turns while the output coil has 110 turns. Assuming the input voltage is 120 volts, what is the output voltage necessary for his appliances to work properly? (This is the standard household output voltage in Zimbabwe.)
