The Full Form of ‘DC’ in Electric is ‘Direct Current’.
Full Form of DC
The full form of “DC” in electric is “Direct Current”. Direct current, or DC, is the continuous flow of electric charge from a high potential to a low potential. It is the form of electricity most commonly used in everyday life, such as in home and car batteries, and for powering small appliances like TVs and computers.
Direct current has been around since 1820 when it was first discovered by Italian scientist Alessandro Volta. Initially, it was only used in primitive telegraph systems but its use quickly spread to various other applications. The popularity of DC power began to wane with the introduction of alternating current (AC) in the late 1800s. AC had several advantages over DC, such as being able to transmit power over longer distances using transformers. However, the development of efficient semiconductor devices has led to a resurgence in the use of DC power for many applications.
One major benefit of direct current is that it can be easily controlled using simple electronic components like transistors and resistors. This makes it ideal for controlling motors and other equipment that require precise control over their speed or position. Additionally, DC power can be stored indefinitely in batteries making it a great choice for portable electronics like cell phones and laptop computers.
Another advantage of direct current is its low losses compared to AC power transmission lines due to reduced line reactance losses when transmitting long distances at lower frequencies. This makes it an attractive option for powering remote applications such as telecommunication base stations located far away from existing AC grids or solar installations where long distance transmission would otherwise be cost prohibitive.
Despite its advantages, direct current still has some drawbacks compared to AC power including higher initial cost due to more complex electrical equipment needed for conversion between AC and DC; limited transmission range; higher maintenance costs associated with more frequent battery replacements; and safety concerns due to increased risk of shock or fire associated with high voltage DC lines.
Overall, direct current remains an important part of modern electrical systems providing reliable power sources for countless applications around the world including motor control circuits; battery storage; telecommunications networks; renewable energy systems; industrial processes; medical equipment; consumer electronics; and much more!
