As the load is applied to a synchronous motor, the motor takes more armature current because

0
A.the increased load has to take more current
B.the rotor strengthens the rotating field casuing more motor current
C.the back e.m.f. decreases causing an increase in motor current
D.the rotor by shifting its phase backward causes motor to take more current
Explanation: The correct answer is the rotor by shifting its phase backward causes motor to take more current.
