In the energy sector, it is often necessary to convert some quantities to others because electrical energy is produced by sources of alternating or direct current. Corresponding consumers are created for them: electric motors, transformer devices, household appliances.

In many industries, as in alternative energy, there is a need to exploit consumers from combined sources. Rechargeable batteries are charged, and electronic devices, computer devices are supplied with direct current or rectified from electric power generators with a rotating electromagnetic field.

The inverse task of the electric motors of the sinusoidal harmonics of household electric receivers from direct current sources is solved by converting electricity into variable using ...

In modern solar power plants, different schemes for connecting current sources are used to transfer the generated electricity to working batteries. They use not the same algorithms, are based on microprocessor technologies, called controllers.

Electricity generated by the solar battery can be transmitted to storage batteries: directly, without the use of switching devices and control devices, through the controller.

In the first method, the electric current from the source will go to the batteries and will increase the voltage at their terminals. Initially, it will reach a certain limit value, depending on the design (type) of the battery and the ambient temperature ...

Nowadays, there are already many industrial devices that are controlled by the GSM (Global System for Mobile Communication) standard — a digital standard for mobile communications or a now familiar mobile phone. This is a burglar alarm, various control cabinets for industrial equipment, or simply separate sockets.

The design in appearance is a regular adapter that plugs into a wall outlet. The load can be switched on by ringing or transmitting.sms by mobile phone. It is also possible manual control using two buttons located on the front panel. The power switched by such outlets, depending on the model, is in the range of 1 - 5 kW, which allows you to turn on almost any load. Multichannel sockets are also available that allow you to control independently multiple loads...

Ventilation of the bathroom and toilet is an integral part of it. Ventilation provides an optimal microclimate in these rooms, both for a person and for objects and interior elements.

Firstly, ventilation significantly reduces the humidity in the room, which is especially true for the bathroom and toilet - rooms with high humidity. Humidity reduction prevents the formation of mold and damage to electrical appliances and interior elements due to increased humidity in the room. Secondly, ventilation eliminates undesirable odors and prevents the growth of bacteria.

Ventilation can be either natural or artificial. In the absence of the possibility of providing natural insulation of the bathroom and toilet, artificial ventilation is used ...

A characteristic feature of the bathroom, in comparison with other rooms of the apartment, is that it has an increased level of humidity, and it is also possible that the elements located on it, including electrics, can splash water onto the wall. Based on this, the installation of electrical wiring in the bathroom is somewhat different from the installation of electrical wiring in other rooms of the apartment. Below, we consider the features of installing electrical wiring and connecting household electrical appliances in the bathroom.

It should be remembered that errors in the installation of electrical wiring in the bathroom, as well as the wrong choice of protective devices, can lead to negative consequences - a person is shocked by electric shock, since electricity and water are incompatible things. Therefore, do not neglect the recommendations and it is better to make the wiring in the bathroom reliable and safe to use ...

Fireproof soldering iron tips require a delicate attitude. In no case can they be cleaned with files or sandpaper, since the protective layer is quite thin, and its damage will lead to an early burnout and wear of the tip. Such stings can only be periodically wiped on a special sponge (sold with other soldering accessories), or on a wet piece of cloth.

Instead of a special sponge, a dishwashing sponge is quite suitable. Naturally, the sponge should be moistened with water. You can moisten the sponge with glycerin (sold in pharmacies), then the sponge will not dry, always remain wet and ready to work.

To clean a non-combustible tip, among other soldering accessories, special tip cleaners are available. This is such a net, not to say a washcloth, made of brass chips in the shape of a ball, into which the sting should be periodically immersed. In this case, excess solder and oxides remain inside the coil...

Modern electronic technology is improving very quickly. The degree of integration of modern microcircuits is such that millions of transistors fit in a single case, but the cases themselves are becoming smaller and smaller. Discrete parts - transistors, capacitors, resistors are also small-sized, lead-free. All this is mounted on boards by SMD surface mounting. The parts are so tightly arranged that it is simply impossible to solder something with an ordinary forty-watt EPSN electric soldering iron.

True, some experts from the soldering iron claim that you can solder anything you want even with an ax. Maybe this is so, but, as they say, not everyone is given. Therefore, it is better, nevertheless, to use a soldering iron, since now there is a very wide selection of soldering tools. And you need to be creative in purchasing this tool. First of all, it is necessary to determine for what work an electric soldering iron is bought ...

In solar energy, batteries occupy a special place, which play the role of an intermediary in the transfer of electrical power to end-users. This can be explained by the fact that the maximum amount of electric energy is generated by the solar battery during intense light exposure that occurs in the daytime.

However, its greatest consumption is carried out with the onset of darkness, when lighting with household appliances is massively used. Batteries allow you to save surplus electricity generated during the day for evening and night use.

Of course, as an option, in the daytime you can turn off part of the working solar modules in the reserve, but this will not solve the issue of evening electricity shortages. Any electric batteries are considered as reusable direct current sources ...
