When preparing for a trip abroad, we take a lot of electronic gadgets with us, such as electric shavers, phones, tablets, laptops, e-books, cameras, MP3 players, etc. But, not everyone knows that in each country there is a different electrical system, in which there are different standards for electrical plugs and sockets, different frequencies, voltages and currents.

Therefore, before traveling abroad, it would be a good idea to find out in advance about the power grid system in the country in which you are going to arrive.

Otherwise, it may turn out that in the host country you will not be able to charge your electronic device and even turn it on to work from the network.

Various types of electrical outlets

Most power supplies for electronic devices such as laptops, chargers, mobile devices, camcorders and cameras have a universal power supply, so they are able to operate at a supply voltage of 100 to 240 volts, and a frequency of 50 or 60 Hz.

Here is an indicative map-diagram of the use of voltage and current frequency in different countries of the world:

As you can see, most electronic devices and gadgets are adapted to work in a wide range of electrical systems in different countries, but there is a very important point related to the type of electrical plugs and sockets in these electrical systems. In different countries, the standards for sockets and plugs are different, so you simply cannot connect the charger to this socket, as it simply does not fit there.

Here is an indicative map-diagram of the use of electrical plugs and sockets by type in different countries of the world:

To protect ourselves from such disappointments, we should take care of this in advance by purchasing the appropriate adapter or adapter to charge this device. Today you can buy a universal set of adapters that are suitable for most countries in the world. But still, before traveling to another country, it will be nice to find out about the standard of the electrical system in it, to find out the standard for plugs and sockets.

Note! There are countries that have different standards for electrical systems depending on the region or area, such as Brazil or the Maldives. In this case, you should check more precisely which standard applies in this particular area of ​​the country. If a country has more than one standard, this will be indicated in the table below, otherwise there will be one entry for the country.

So, for starters, let's look at all the world's standards for electrical plugs and sockets with the attached photo and a more detailed description. Here you can find out what, for example, an American outlet, European, Japanese, Australian, etc. looks like.

Types of electrical sockets and plugs from around the world

Type A - This is an American electrical socket and plug. It has two flat parallel contacts. Used in most countries in North and Central America, in particular in the United States, Canada, Mexico, Venezuela and Guatemala, as well as in Japan. And also everywhere where the voltage is 110 V.

Socket and plug type A

Type B is the same Type A connector but with an additional round ground pin. Commonly used in the same countries as the Type A connector.

Socket and plug type B

Тип C - This is a European socket and plug. It has two round parallel contacts. It does not have a third ground pin. This is the most popular outlet in Europe, except for the United Kingdom, Ireland, Malta and Cyprus. Used where the voltage is 220V.

Type C socket and plug

Type D is an old British standard with three round pins set in a triangle shape with one pin being thicker than the other two. This socket standard is used for maximum current, used in India, Nepal, Namibia and Sri Lanka.

Type D socket and plug

Type E - This is a plug with two round pins and a hole for the grounding contact, which is located in the socket socket. This type of socket is currently used in Poland, France and Belgium.

Type E socket and plug

Type F - this standard is similar to type E, but instead of a round ground pin, two metal clips are used on both sides of the connector. This type of socket is used, for example, in Germany, Austria, Holland, Norway and Sweden.

Socket and plug type F

Type G - This is a British socket with three flat pins. It is currently used in the UK, Ireland, Malta and Cyprus, in the world, for example, in Malaysia, Singapore and Hong Kong. Note - This type of outlet is often supplied with an internal fuse built in. Therefore, if after connecting the device it does not work, then the first thing to do is to check the condition of the fuse in the outlet, perhaps it is in it.

Socket and plug type G

Type H - This socket is only used in Israel and the Gaza Strip. It has three flat pins, or in the earlier version the round pins are arranged in a V shape. Not compatible with any other plug. It is intended for voltage values ​​​​of 220V and currents up to 16A.

Socket and plug type H

Type I - this is an Australian socket, it has two flat pins, like in the American type A connector, but they are located at an angle to each other - in the shape of the letter V. There is also a version with a ground contact. This type of socket is used in Australia, New Zealand, Papua New Guinea and Argentina.

Type I socket and plug

Type J This is a Swiss plug and socket. It looks like a Type C plug, but has an extra ground pin in the middle and two round power pins. Used in Switzerland and abroad in Liechtenstein, Ethiopia, Rwanda and the Maldives.

Type J socket and plug

Type K - This is a Danish socket and plug, similar to the popular European type C socket, but additionally has a grounding contact located at the bottom of the connector. It is the basic standard mainly in Denmark and Greenland, as well as in Bangladesh, Senegal and the Maldives.

Socket and plug type K

Type L - This is an Italian plug and socket, it is similar to the popular European type C socket, but has an additional round ground pin located in the center, two round power pins are unusually in line. Such an outlet is used in Italy, as well as Chile, Ethiopia, Tunisia and Cuba.

Socket and plug type L

Type M - This is an African socket and plug with three round pins arranged in a triangle shape, while the ground pin is clearly thicker than the other two. It looks like a type D connector, but it has much thicker contacts. The socket is designed to power devices with current up to 15A. Used in South Africa, Swaziland and Lesotho.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Random news from the Archive Nanoparticles catch light 20.07.2008 Scientists from Sweden have learned how to create periodic nanostructures in a single laser pulse. A layer of nanoparticles, such as gold or silver, is poured onto a thin membrane, and then it is illuminated with a pulsed laser beam. Nanoparticles absorb light, the free electrons contained in them begin to oscillate together with the so-called plasma frequency. If the particle size is chosen correctly, this frequency will be just what is needed to excite similar vibrations in the membrane and turn it into a waveguide. As a result, the energy of the laser pulse is transferred to the membrane, and a standing wave appears on it. In places of its crests, the temperature can be very high, so those nanoparticles that are located above them will melt and flow into the cold troughs of a standing wave, where they will freeze again. So on the membrane you get a periodic relief. The whole process takes a few nanoseconds, and the relief period can be either longer or shorter than the radiation wavelength. “By choosing the parameters of optically active particles, we can turn a nanometer-sized membrane or fiber into a waveguide. By the way, using plasmon resonance, you can significantly increase the efficiency of light absorption in solar cells,” says Dinko Chakarov, the author of the work.
