Electrical transformers are devices that transform alternating current from input voltage to a desired output voltage. They are used in a variety of applications, such as regulating voltage in one circuit, powering electrical equipment, and isolating two circuits.

Electric cables are devices used in the electrical field, to allow the power supply of various types of equipment. However, their sizing is a very delicate operation, which requires careful evaluation. In this article we will try to understand how to calculate the cross-section of electrical cables, using a sizing table.

The carrying capacity of an electrical wire (or short circuit current) is the maximum amount of current that can pass through an electrical wire before a short occurs. This is a fundamental measure of the safety of the electrical system.

The first thing to do is to perform an accurate diagnosis of the switch. Check for visible damage, such as a loose clutch or other mechanical damage. The most common cause of a stuck switch is lack of lubrication. This means that the oil inside the switch may be depleted or even absent. To check for this possibility, you need to remove the switch from the wall and open it. If the oil is missing, you need to purchase a suitable lubricant for the switch.

Relays are electromechanical devices used in various fields of electronics, such as industrial automation, for controlling electrical equipment, turning motors on and off, turning lights on and off, etc. There are several types of relays, including monostable and bistable relays. In this article we will explain the differences between the two types of relays, when and how to use them.

Type F RCDs are protective devices that allow you to protect against an overvoltage or short-circuit. These devices help increase the safety of electrical systems in both your home and business. This is a really useful solution to avoid damage to equipment and harm to people.

Schuko outlets are a two-prong type of electrical outlet that is grounded for the device, while regular outlets are a two-prong type of outlet that is not grounded. Both types of sockets are widely used in many European countries, but the Schuko socket is more widespread and is generally used in all European Union countries.

A TV splitter is an electronic device that allows a television signal to be split into multiple outputs. This is an ideal tool for people who have multiple TVs sharing the same signal, such as when you live in a house with several apartments. A TV splitter can also be used to connect an antenna or cable to multiple TVs at the same time.

Cells and batteries can be subject to rapid oxidation of the electrical contacts due to their exposure to the environment. Left untreated, these contacts can become damaged or even unusable. In this article we will look at the causes of oxidation and how to prevent it, and how to remove it when present.

Choosing an outlet or TV antenna cable can be a bit tricky. One of the most important aspects to consider is the selection of the type of male or female connector. The wrong choice can lead to problems with the installation of the socket or cable. In this article, we will look at the difference between male and female, the advantages and disadvantages of each, and help you decide which one to choose.

An astronomical switch is a device that is used to control the on and off of lights, household appliances or other electrical appliances based on external light conditions. It is a safety device that can be installed indoors and outdoors and is able to detect the amount of light present outside, and then activate or deactivate the electrical devices based on the external light conditions.

A capacitor is an electrical device that is used to store electrical energy. It consists of two adjacent electrodes, separated by a dielectric, which allows electric charge to build up on them.
