LDR It is an electrical resistance that depends primarily on the rays and brightness of light. The greater the rays of light or the sun, the greater its value in resisting electrical current, and vice versa. It is widely used in public lighting cir...

What is a RCD breaker | how it's Works   What is a RCD breaker | how it's Works Today we studied about the most important electrical element, which is the differential cutter, also known as a Residual Current Device breaker, The differential cutter plays an important role in protecting electrical circuits and wires from the leakage of electric current and short circuits. It was necessary to find a solution to the problem of electrification and electric shocks and prevent electrical fires which the electric rationing is exposed, and since the need or the invention, the so-called differential cutter was invented to ensure and protect the electricians and ordinary people from electric shocks, whether by direct or indirect touch. The differential cutter components:  generally consist of four inlets, two poles to enter the phase wire, the neutral wire and the two poles the outside to exit the same wires, the phase wire and the neutre wire. By measuring the strength of the current E...

The importance of grounding , operation, installation.   The importance of grounding , operation, installation. The grounding process is considered one of the most important steps that must be accomplished when installing an electrical network, whether in household electrical installations or in industrial facilities.  And what are the types of grounding process?  The most important uses of the grounding process?  Tools needed to complete the grounding process?  All these questions we will try to answer in this small educational article. Follow the explanation with me. Definition of earthing :  The grounding process is the connection of an electric wire between electrical appliances and the ground away from the source of electrical energy through what is called the electrode, which is a rod with a length of one meter or more, depending on the type of place for which the grounding process is to be established. It is made of brass, as the ground voltage is eq...

Ohm's Law equation, explanation Ohm's Law equation, explanation Ohm's law is one of the basic laws on which electrical  and electronics engineering in general are built. This law explains the relationship between voltage, current and electrical resistance , In this article, we will show you some mathematical equations associated with this law. Definition of Ohm's Law:  Ohm's law is a relationship between the potential difference and the electric current, as the flow of electric current in a conductive wire is directly proportional to the voltage applied to it, and thus the electric voltage is equal to the current strength multiplied by the resistance of the wire, It can be mathematically expressed as ("V = I * R )  and this picture shows all the relationships between voltage and electric current  : Ohm's Law equation  This law helps to explain how these three key parameters are interconnected and influence each other within a circuit. Ohm's law units:  ...

Working principle of Thermistor resistor , symbol   Working principle of Thermistor resistor , symbol Welcome to the Electron Tips blog. In today's lesson, we will provide you with a simplified explanation about thermal resistance, or thermistors, which are considered one of the most important electronic elements, as the latter is related to changing the temperature of the medium in which it is located. Thermistor ? What is the principle of thermal resistance working within electronic circuits What are the types of thermal resistors? . Definition of thermistor:  Thermal resistance is an electronic element whose value changes with the temperature of the medium in which it is located. The higher or lower its value, the greater the resistance to electric current. It can be classified as one of the temperature sensors that measure the temperature of electronic elements.
