The electric braking system employed with dc shunt motors, in which the armature connections are reversed so that the motor tends to run in opposite direction is called the ____braking

A dc shunt motor is driving a constant torque load with normal excitation. If the filed current is halved then the motor will run at
A dc shunt motor is driving a mechanical load at rated voltage with normal excitation. If the load torque is increased to double of the normal one, the speed of the motor will
