When connected to a closed circuit power supply (generator, battery, battery), a potential difference is created between the ends of the circuit under which the electrons begin to move from one end to the other. The other circuit, trying to assume a state of equilibrium. But this phenomenon would have no practical use if, when electrons move around the conductor, the magnetic field did not appear. The magnetic fields of the individual electrons are added to a large one, which allows us to increase it to the desired values when adjusting the voltage. The higher the potential difference (voltage), the faster the electrons move, the more magnetic the conductor is. The magnetic field acting on the surrounding objects is capable of transferring their energy. It is the basis of transformers, electric motors, magnetic coils, etc. 

The electrical current phenomenon can be represented as a familiar physical phenomenon. Imagine a water pipe (or a river). The bed on the river is like an electric cable. The larger the channel of the river, the greater the amount of water (current) that can pass through it per unit of time. Water movement is comparable to electric current. And the potential difference (voltage) is comparable to the difference in height between the river mouth and the source. The pipeline walls, the river banks, and the riverbed stones play the resistance role. The greater the resistance, the slower the flow of the river. By representing this option, you will understand the basic concepts of the electrical current phenomenon in part. 

How DC and AC Is Divided Into Constant, Alternating Current 

The direct current in time does not change direction. An example would be a flashlight battery, or a battery, where there is always a plus and minus. (They are normally marked with the appropriate symbols) The alternating current differs from the constant current as it changes direction with a certain periodicity (frequency). This current, with a frequency of 50 Hertz, flows into its socket when it connects an electrical device. The current frequency is a value determined by the relationship between the number of complete current and time change periods. Measured at Hertz (Hz). 

If your house is old – fashioned, there are probably only two cables: phase and zero. So no one confuses them, they’re marked with different colors. Zero is blue for AC, “earth” is yellow-green, the phase is any other color. No specific color is assigned to the phase, but there may be three phases in your home, depending on the wiring scheme. 

For the circuit to close, that is, to keep the operating mode of the device, a zero is required in the network. The ground connection provides additional protection against electrical shock. For example, while the washing machine was working, the cable fell inside and fell on the body with the bare end. Naturally, the washing machine has a dangerous voltage close to 220 V. In this case, the risk of electrical shock is high. Since the ground cable’s resistance is less than that of the human body, the current will follow the easiest path by itself: through the ground wire. As a result, it will save you from injury. And it immediately disconnects the emergency network from the voltage in the presence of the DDR. 

It is important to remember that the ground wire only protects when properly connected! In the case of installation infringement, this may present an additional risk. Whatever the color of the cable, be sure to check the absence of voltage before touching it. We don’t know who got the wiring at home, a teacher or an amateur. 

It is important for all Electrical Contractors Cicero IL to know where you have the right to repair the electrical wiring. The power contract stipulates that the electrical network of the consumer starts with the upper contacts of the machine installed in front of the meter. As a result, your property also belongs to the electricity meter. However, since the meter is a device whose wiring diagram has to be guaranteed and its operation guaranteed, it is usually sealed. We have the right to replace the electricity meter ourselves, but only if we have previously invited a representative from the electricity supplier organization to remove the seals. 

Remembering the basics may be enough. If I have forgotten something or have questions, write them in the comments or comments form. I’m going to read it and answer.
