If you are going on vacation, make sure that you will not be left without your smartphone if it is discharged. Sockets are not the same everywhere, like mains voltages. If the supply voltage in this country is suitable, it remains to acquire such an adapter or to find out in advance where to buy it on the spot or order charging with such a plug. In this article we will talk about the types of outlets and how many volts are in the outlet in different parts of the world.

All countries of the world use alternating current in their electrical networks. The difference lies in the voltage and frequency of the network. Two common frequencies are distinguished: 50 Hz and 60 Hz. Voltages also differ - 100, 110, 115, 120, 127, 220, 230 or 240 Volts. In this case, the voltage and frequency can be different in different regions of the same country, as, for example, in the eastern part of Japan, a network with a frequency of 50 Hz, and in the western - 60 Hz. This may be due to the fact that electrification occurred at different times or part of the country was part of another country ...

Sockets are in every apartment, and they are used many times a day, they connect electrical appliances. Sometimes situations arise when you need to replace the outlet, transfer it, or simply remove it for the duration of repair and wallpapering. Although this is not difficult to do, safety precautions must be followed to avoid electric shock. In this article, we will look at how to remove a wall outlet and disassemble it.

To carefully dismantle the outlet, you need to know its device. It differs depending on the specific model and manufacturer, but, in general, the design is the same. Sockets are built-in and overhead. The built-in ones, as the name implies, are located inside the wall in the recess, and the invoices are fixed outside. Often overhead sockets are used if external wiring is laid or on thin walls, partitions, on furniture elements. The socket consists of four main parts.In the wall or in the socket, it is attached by the legs ...

Normal operation of a computer and Internet network in a room is often impossible without installing so-called information sockets. Using these outlets, computers and other network devices are connected to each other or to the network using twisted pair cables. This is especially true for large buildings, where there are many computers, which can also often change places due to rearrangements, relocation of offices, etc.

Computer sockets are also needed in residential premises, where Wi-Fi is not always enough, especially when there are several computer (and other Internet-requiring) places, and in each case the highest possible quality of connection is required. The task is solved simply - these sockets can be placed in each room, especially since their installation is absolutely simple, if you have the appropriate knowledge and skill. Let's talk about all this next ...

To connect various household appliances, industrial equipment or just gadgets for charging to the AC mains, we are used to using wall outlets. If the household outlet meets the specifications of all our requirements, then this is very good, such an outlet becomes our favorite outlet for powering this or that device, and we get used to powered this device from it. The outlet is in a suitable place, at a convenient height, the plug sits comfortably in it, maybe there is a backlight, etc.

A favorite outlet can become quite easy, because today many manufacturers produce them using various materials. At a minimum, outlets are overhead, recessed, or even hidden.In addition, sockets may have additional useful features that will increase comfort and provide additional reliability for using this socket for its intended purpose in a selected location ...

Arriving at the electronics store, you sometimes notice that your eyes are scattering from the number of different outlets that are presented on the window. Overhead and domestic, expensive and cheap, with and without curtains, etc. Which choice? A flair seems to suggest that a good and high-quality product, in principle, can not be cheap.

On the other hand, what might be so unusual in the design of a seemingly ordinary outlet, which makes it so expensive? Although the bitter experience reminds: “once I took the cheapest outlet, it cracked during installation right away”. The answer suggests itself. More expensive sockets are really better, and it would be better to take a closer look right at the store, what is so useful hidden in the design of an expensive socket. The bottom line is that the designs of new outlets, from manufacturers who value their reputation, are designed taking into account shortcomings ...

Now so-called smart devices are very popular. In most cases, their main function is the ability to remotely turn on and off via the Internet or mobile network. But also with the help of various solutions it is possible to implement remote control of the outlet, respectively, and any electrical equipment. In this article we will look at ways to solve this problem.

Using a radio relay, they usually operate at a frequency of 315 or 433 MHz. This option is interesting in that it allows you to embed the module both in the device that you will control and in the junction box. Radio relay come with a different number of channels and its good versatility and ease of implementation of the project as a result. The disadvantage is the range. Wi-Fi sockets and relays are also easy to use and versatile. There are many smart sockets on the market, which are an adapter that can be installed in a regular socket ...

Work as an electrician is not always assembling and repairing circuits and laying cables. To lay a line, install sockets, hang fixtures, you need to properly make holes or hollow out a recess. To do this, you need to know the main types of drills and the features of their use. In this article, we will look at how to drill a hole in concrete, wooden walls and metal surfaces.

In everyday life, for basic construction work, use screwdrivers, drills, impact drills and perforators. A screwdriver is a small device designed to wrap screws and self-tapping screws in non-solid materials. They are also suitable for drilling drywall chipboard, plywood, wood and its other derivatives. Suitable for drilling not too thick metal. They are wireless and wired. The characteristics of cordless screwdrivers usually indicate not the power, but the battery voltage ...

A backlit switch is a convenient and beautiful solution. It is needed in order not to look at night with your hand where the light turns on, randomly clapping on the wall. But with the transition to energy-saving, and then to LED lamps, many encountered the problem that the light is blinking or dimly lit with such a switch. The backlight also causes this effect. In this article, we will explain why the LED bulbs flash when the light is off.

The switches set the backlight of one of two possible types: a neon bulb (glow discharge indicator) or an LED.Light indication on a neon bulb, as well as on LEDs consumes low current (units of milliamps). The neon indicator lights up when the switch is in the “OFF” position, that is, when its contacts are open. When you press a key, closing its contacts, the lamp turns on and the display turns off. The logic of work is elementary ...
