Q
As the load is applied to a synchronous motor, the motor takes more armature current because
-
A
A. The increased load has to take more current
-
B
B. The rotor by shifting its phase backward causes motor to take more current
-
C
C. The back e.m.f. decreases causing an increase in motor current
-
D
D. The rotor strengthens the rotating field casuing more motor current
Correct Answer:
B. B. The rotor by shifting its phase backward causes motor to take more current
