Answer the following statement(s) true (T) or false (F)

1. The magnetic polarity of the field system is arranged so that the polarity of any particular field pole is opposite to that of the poles adjacent to it. 2. To reverse the direction of the armature rotation of a DC motor, the current direction in both the field and the armature must be reversed. 3. As a DC motor armature starts to rotate, the CEMF increases and the line current decreases. 4. Because torque depends on the strength of the magnetic field of the armature, which, in turn, depends on the armature current, any increase in mechanical load requires an increase in the armature current, more load, slower speed, higher differential, and more current. 5. The terms speed control and speed regulation can be used interchangeably
