Direct Current and Alternating Current
Both AC and DC are types of current flow in circuits. Alternating current is a category of electric current, in which electrons switch directions back and forth. The direction changes are at regular intervals. In most parts of the world, the standard current is 50 cycles per second. DC, on the other hand, is a type of current in which flow of electrons in a circuit are constant in one direction (Wang, Chen, & Li 2016). Therefore, the two types of current are opposite of each other. DC and AC have several disparities and similarities; this paper will compare and contrast the two types of currents.
How AC and DC are commonly used
DC is used on common portable appliances such as mobile phones and flashlights. Additionally, because it has a direct flow of current, it gives room for the transfer of information. For this reason, it was used in traditional telephone cables. Moreover, all portable solar system produces direct current. Other use of DC includes automobiles and aircraft applications. AC, on the other hand, is commonly used in transportation and production of electricity. Almost all households are connected to the AC grid. Additionally, the power is used for most households’ appliances such as the dishwashers, refrigerators, and toasters. Therefore, AC is commonly used on items that require storage of energy and therefore potable. On the other hand, DC is used by electronics that do not need to store energy.
Advantages and disadvantages of AC and DC
One of the advantages of DC is that unlike AC it can hold current for a long time. This...
