Electrical Power Applications

Provide a 9 pages analysis while answering the following question: Electrical Power Applications. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. However, the DC gets its power from a direct current. Some of the sources of direct current include batteries, DC power supplies and AC-to-DC power converter. Further, the DC wound field motors constitutes a brush and a commutator. These two helps in complementing on the maintenance of motors while also limiting on the speed. Further, the commutator and the brush also help in reducing the life span of the DC motors. On the side of AC, the induction motor does not associate with&nbsp. the use of the brushes nor the commutator. The absence of the brushed contributes to the long life expectancies of AC motors. Another main difference exists in the speed control associated with the two. The control of the speed of a DC motor arises from the existing armature winding associated to current. However, the control of the AC motor arises from the action of the fluctuating frequencies. The adjustable frequency drive control helps in varying the frequency of AC motor. The electromagnetic induction occurs when there is a electric current, which passes through a fluctuating magnetic field. In an AC generator, there is a periodical reversal of direction in the electrical current while a DC involves the flow off current in a specific direction. The difference existing between the AC and DC generators leads to the differences arising in the relationship between output voltage and output power. The design difference occurs in the way the current flow design occurs in both. In AC generator, the coil carrying the current flow is always in a fixed state while the magnet is in motion. The poles of the magnet are what cause the alternating current sine it force the current to achieve a flow in opposite direction.
