Question
If the strength of the main field increases, the CEMF developed in the armature will
O increase
O decrease
O stay the same
Transcribed Image Text:If the strength of the main field increases, the CEMF developed in the armature will O increase O decrease O stay the same
The reason why the starting torque of a series motor is higher than a shunt motor is
because the series motor has
O more current flowing through its armature
O a stronger net magnetic field around both coils during the inrush of stator current
