As we enter into the broader coverage of Alternating Current (AC) and Direct Current (DC), let us first understand what current is how it is important as a major subject of Physics, and how it is distinguished into AC and DC. It is obvious that the current is a very important topic in Physics because the current is a crucial element that runs our lives and the entire world. Learning about current and its divisions, Alternating Current and Direct Current is crucial in understanding several related and other topics or chapters. So, in order to move on to other topics or chapters, the students must focus on understanding the above concepts first. In the below sections, you will understand how AC and DC work, and how can one convert alternating current into direct current.<\/p>\n

The current flow in a circuit often changes based on the type of application or its uses. Electric current travels in two paths, one as an alternating current (AC) and direct current (DC). The flow of current in AC and DC paths primarily symbolizes the definition or nature of these currents. The difference is seen in the direction in which the electrons flow. In direct current or DC, the electrons travel steadily in one direction. However, in AC or alternating current, they repeatedly change directions, moving forward and then backward.<\/p>\n

Let us also understand the characteristics of alternating current or AC, and the characteristics of direct current or DC<\/p>\n

What is AC or alternating current?<\/strong><\/h2>\n

The current inside a circuit, which changes direction` periodically, from forward to backward is known as the alternating current. This type of current is very commonly used in household equipment, such as fridges, pressure cookers, microwaves, and many more. The alternating current or AC, when observed on a graph, forms a Sine Waveform, which represents curved lines, that describe the electric cycles that are measured per second.<\/p>\n

The most important feature of the alternating current or AC is its ability to be transported over long distances easily without any issues or loss of current. The AC is measured in Hertz, and the frequency of AC is between 50 to 60 Hz.\u00a0 AC was first tested back in the year 1832, by following the Principles of Michael Faraday, by making use of Dynamo Electric Generator.<\/p>\n

What is DC Current or Direct Current?<\/span><\/b><\/h2>\n

As you can understand from the above section, the direct current or DC, unlike the Alterntating current or AC does not change direction periodically. So, this means this type of current flows in a single direction steadily. And this is one of the main reasons why it is actively used to charge batteries or supply power to other common electric devices. For example, electric devices like a flat-screen TV, electric Vehicles, etc. Moreover, in the DC current generally, the electrons will transfer from negative to positive terminals. Besides, the electric devices that use AC generally, will use the DC to charge or power their devices. Unlike the AC, the DC is resistive in nature, and it does not have polarity. Apart from this, the frequency of direct current remains zero.<\/p>\n
