If the rotor of an electrical induction motor is turning near the cyclic speed of the induced rotating electromagnetic field in the primary under no-load conditions, the interaction of the primary and secondary electromagnetic fields is __________.
Because of the low frequency of the induced voltage and the resulting current flow in the rotor circuit are both of __________ value, the impedance reflected into the primary appears as an open secondary in a transformer — very __________ value.
The current drawn in the primary (stator) windings, because of the value of the reflected impedance, is also of __________ value.
A) low; minimal; high; minimum
B) minimal; low; high; minimum
C) minimum; minimal; low; high
D) high; minimal; low; minimum
