The alternator from the portable power supply is disconnected from the transformerand lamp. Explain why the handle of the alternator becomes much easier to turn.

A 3-phase, 60 Hz, Y-connected, AC generator has a stator with 72 slots, each slot contains 10 conductors. The conductors of each phase are connected in series. The flux per pole in the machine is 0.04 Wb. The speed of rotation of the magnetic field is 720 RPM. What are the resulting RMS phase voltage and RMS line voltage of this stator? Select one: O a. None O b. V = 1279.5 Volts and VT = 1279.5 Volts O c. V = 1279.5 Volts and VT = 2216.2 Volts O d. V = 1809.5 Volts and V- = 3134.1 Volts O e. V = 2216.2 Volts and VT = 2216.2 Volts Clear my choice
