Answer:
To get a direct current (DC), a split ring type commutator must be used. With this arrangement, one brush is at all times in contact with the side moving up in the field, while the other is in contact with the side moving down.
The direct current (DC) is always flows in one direction, whereas the alternating current (AC) reverses its direction periodically.
