Your phone's battery is almost empty. Then, back at the hotel - disaster strikes. In this video we take a look at the different voltages and sockets in different countries. When electricity first became available to households in the 1880s, it was mainly used for lighting. Over the next several decades, more devices became available, and so plugs and sockets were required. Initially, the plugs had two contact pins, a phase and a neutral conductor. To increase the safety of plugs, some countries have introduced a third ground pin.This design is safer because the current can flow to earth because there is a wire inside the device that touches the metal case of the device. It basically reduces the risk of electric shock if something goes wrong. However, not all countries have introduced this third ground pin on their plugs. There are now 15 different types of plugs and sockets worldwide! To learn how a British plug is wired, watch this video: In addition to the different plugs and sockets, there are other important differences between the world's power supplies. Different countries use electricity at different voltages; on the American continent and in Japan the voltage is 120 volts, while in Europe the voltage is between 220 and 240V. Why is there no uniform tension across the world? The answer lies in the story. Two men were instrumental in the introduction of electricity: Nikola Tesla in Europe and Thomas Edison in America. Tesla preferred to use electricity at 240V, which made it possible to travel long distances without much energy loss, while Edison preferred 110V, which was considered safer. Remember that the US uses the Anglo-American measurement system while Europe uses the metric system. This also influenced the values ​​used. Today's systems of using and transporting electricity have evolved from the original ideas of these two men. Fortunately, most modern devices work with both voltages. All you have to do is take a look at the label on the device and it will tell you the voltage range the device can operate in. For example, this device works with voltages between 100 and 240 volts. So you need a plug adapter, but you don't have to worry about the voltage. To learn more about the power grid and power transmission, watch this video. It explains the use of transformers to change the voltage of electricity and why they are necessary. So if you're going to another country, make sure you have the right adapter for your plugs. On the one hand, so that they also fit and on the other hand, so that the voltage is compatible.
