History of DC-

Thomas Alva Edison invented DC current in the 18th century. You would be surprised to know that in the early 19th century, DC current was used for every job in America.

Right now the DC current used in the domestic equipment in our home is converted from AC current only.

Like in our home television we supply AC current but with the help of a transformer our television converts it into DC and then use

We can easily convert AC to DC and DC to AC as per your needs. A rectifier is used to convert AC to DC while the inverter is used to convert DC to AC.

Benefits of Direct Current-

  • The biggest advantage of DC current is that it can be easily stored and today DC current is used everywhere and it has changed our life to a great extent and its quality can be easily stored. Could have made it so useful.
  • Many domestic types of equipment operate more efficiently when operated on DC, this is also a big advantage of DC current.
  • DC is very useful when it comes to power transmission, very high voltage DC current is used in very long-distance power transmission.
  • Another advantage of DC current is that when we use domestic equipment, its maximum voltage level is from 12 to 48, then it is not dangerous in any way, meaning you cannot be shocked by this current.
  • One of the biggest advantages of direct current is that you can use it anywhere with the help of batteries and solar cells you can use DC instantaneously anywhere.


The biggest disadvantage of DC current is its transmission loss. At low voltage, the transmission loss is very high, as if you want to take 12 volts of power even 20 meters away, then the power loss becomes very high.

Another disadvantage of DC current is that it is easier to convert AC to DC while it is a bit difficult to convert DC to AC.


uses of Direct Current-

  • The largest use of DC current is in automobiles. You cannot imagine this best automobile sector today without DC current.

By this process, any data can be compressed before storing or transmitting it, without losing any information.

Data compression is a digital signal- process in which any data is compressed into bits before transmitting or storing it so that it uses less space and net.

From a simple exam, we can understand that if you have to transfer a file of 1GB to a friend, how long it will take you or how much data will have to be spent,

but if you compress the same file and assume that its If the new size is 250 MB, then you can understand how easy it became to transmit it.

Types of Data Compression-

Two types of methods are used for data compression

Lossless Data Compression- 

Under this data compression method, when you compress the data, there is no loss of information, not even a single bit.

Lossy Data Compression- 

In this data compression method, some bit of information is lost, but the method of this data compression is done on files of that type where some beats information flame also does not matter.

For example, in sending images, most of such data compression method is used because even if some bits of information are lost from a JPG or PNG file, the image will still open.


Benefits of DC- Data Compression- 

  • The biggest advantage of data compression is that file transfer is faster.
  • After compressing the data, you need less space to store any file.
  • One major advantage of data compression is that it works for both your time and expenses.


DC- Deputy Commissioner

The DC full form or meaning in the Administrative term as Deputy Commissioner.
