![]() While many devices today are relatively universal, this can’t be said for all. If you’re looking for a travel adapter to purchase for your trip to Korea, I will also cover that in today’s post.Īlthough power plugs are deceivingly simple, there are some factors to keep in mind that many people overlook. In this article, I will introduce Korea’s power plug and discuss everything that you need to know before visiting the country. If you haven’t travelled before, this aspect may not even cross your mind! From my own experience, however, arriving in a country and not being able to charge your essential devices is incredibly frustrating. If you travel a lot, you’ll likely know that having a good power adapter is essential. While many things are universal in 2022, power plugs are not one of them. However, what about the former? What is Korea’s power plug? The latter is easy to sort out with a Korean SIM card. That means ensuring that we always have sufficient battery and that we have an internet connection. We won’t be able to answer every question, but we will do our best.With how much most of us rely on electronic devices these days, it’s essential that we are always able to use them. Hello, curious kids! Do you have a question you’d like an expert to answer? Ask an adult to send your question to Please tell us your name, age and the city where you live.Īnd since curiosity has no age limit – adults, let us know what you’re wondering, too. So for the foreseeable future, if you’re getting ready for a trip, don’t forget to pack your adapters. The bottom line is that countries might support the idea of a global standard, but no one wants to change theirs. Not surprisingly, these countries would rather spend that money on something else. ![]() But it would require countries that don’t already use that standard to spend billions of dollars to change their outlets, the way they build buildings and even the way they manufacture certain appliances. Now that most homes in the world have access to electricity, adopting one global standard would be more convenient than having different types of plugs. ![]() So because different countries adopted innovations like these at different times, the plugs that they used changed throughout the years. used these plugs for some appliances, they didn’t become the standard in homes until 1971. Many countries adopted these grounded plugs immediately, but they didn’t always make them the rule. Engineers developed the idea of a ground pin to make plugs safer in the 1920s. People thought they made the plug fit more securely in the socket.Įnglish YouTuber Tom Scott explains why he thinks British plugs are the best.Īt first, plugs in the U.S. Round pins were another early innovation in plugs. Since the copper that’s used for electric wires is expensive, higher voltage could save money. And less current allows for thinner wires. At a higher voltage, electric companies can deliver the same power with less current – picture a narrow stream flowing quickly compared to a wider stream flowing slowly. Companies in Europe realized that supplying power at 220 volts instead of 110 volts would be cheaper. This is still the standard in the U.S., even though actual voltages on our system tend to run a bit higher.īut when people started to build power grids in other countries, they tried to make improvements. Most of the things that ran on electricity back then – mainly lights – worked best at 110 volts. in the 1880s, the voltage delivered to homes was established at 110 volts. When inventors like Thomas Edison, George Westinghouse and Nikola Tesla built the world’s first modern transmission grid in the U.S. You can think of it like running water: It might be a trickle, or a stream, or a flow so fast it can knock you off your feet. The higher the voltage, the higher the pressure. To push current through the wires, electrical systems create a pressure called voltage. This feature is called grounding, because if electric current escapes from the wires that normally carry it, a special set of wires leads it from the center opening to a rod buried deep in the ground. The third opening in the middle of the outlet is called the “ground.” It helps to keep you safe from electric shock if something goes wrong with the plug, or if a wire gets loose in whatever you’ve plugged in. The current flows from the “hot” side through the lamp and back to the “neutral” side. In the U.S., the slot on the right side of an electrical outlet is called the “hot” side and the slot on the left is “neutral.” When you plug in a lamp and turn it on, it completes a circuit that allows electric current to flow and light the lamp. To understand why electric outlets aren’t all the same, you need to know how a plug works. Department of Commerce and are for identification only. Three of the 15 major types of electric plugs in use around the world.
