Today, every one uses computers, TVs and refrigerators. But have you ever considered that many small electric appliances or chargers have three pins rather than two? The third-pin or Prang circuit is not generally connected, but is connected to the device’s external conductive parts.
Have you ever thought why this happens? If not, we tell you that the three-pin plugs are made from the point of view of human rights completely protected. The electric wave works in a circuit and if there is three pins in a plug, top thick part connect to the chassis of the electronics product. However, a pin of the plug is based on the hot slot and the second neutral and third power Works to control the power.
Those household products that use 110 or 220 watt power, if they get more voltage of electricity suddenly, there is possibility of burning, and in this case the third pin protects them.
Similarly, complete the power cycle with Neutral Pin. On the other hand, the third-or-prang circuit is not usually connected to the circuit, but it is connected with the external conductive parts of the device that are taken from the ground. In this case, this third line is unnecessary, but in countries like some countries of Asia where low voltage of electricity or more, it must be used there. Because it prevents neutral and hot pins from connecting the device to external parts, and thus reduces the risk of intimidation.
