Back e.m.f.

Mutually induced e.m.f.

Self-induced e.m.f.

None of these

Differentially compounded motor

Series motor

Shunt motor

Cumulatively compounded motor

All of these

Operating speed

Starting torque

Full-load current

Decrease

Increase

Become zero

Remains same

Motor will come to stop

Nothing will happen to motor

This will make armature to take heavy current, possibly burning it

This will result in excessive speed, possibly destroying armature due to excessive centrifugal stresses
