Question
1.  A 3-phase synchronous motor with negligible losses is connected to the supply at rated frequency and constant terminal voltage 'V'. The induced emf of the motor is designated as E. If the motor is now gradually loaded to its rated power, adjusting its excitation to obtain, say 0.8 leading power factor operation, then E-phasor would
Options:
A .  be less than V-phasor and also lead V-phasor
B .  be greater than V-phasor and also lead V-phasor
C .  be less than V-phasor and also lag V-phasor
D .  be greater than V-phasor and also lag V-phasor
Answer: Option A
