When looking at any circuit, whether electrical or electronic, we will find a number of electrical resistors distributed in more than one place, and this indicates their great importance and the role they play to complete the circuit and carry out the required work. Regardless of their different types, they can often be distinguished by a cylindrical shape with colored lines indicating the The value of the resistance, which makes using it very easy. However, if you want to know how electrical resistors work, you must address the topic from all its aspects and in a little more depth.<\/span><\/span><\/p>\n

Definition of electrical resistance<\/span><\/span><\/h2>\n

It is one of the basic parts used in electrical circuits to limit the electrical current passing through it. <\/span>Various materials are used in their manufacture, such as carbon, metal oxides, metal films, and current-resistant wire, and they are made in various sizes, including large ones made of wire, some with terminals, all the way to small types used in electronic circuits. <\/span>As a result of the different types of electrical resistors, each type is characterized by its own properties and characteristics, and therefore each type is used in a specific field.<\/span><\/span><\/p>\n

In order for the electrical circuit to work as expected, the most appropriate type of resistance must be chosen, although the value of the resistance is the same regardless of its type; <\/span>Their properties vary and their performance is affected in some circuits depending on their type.<\/span><\/span><\/p>\n

Principle of electrical resistance<\/span><\/span><\/h2>\n

It is known that when an electrical voltage is applied between the two ends of a conducting material, an electric current will arise in it resulting from the movement of free electrons present in the structure of the conducting material from the point with low voltage to the point with high voltage, where during their movement they collide with the atoms of the material that prevent them from moving. This is called electrical resistance.<\/span><\/span><\/p>\n

Since the tension applied to the conductive material is directly proportional to the current passing through it, the resistance can be considered the ratio of the applied tension to the current, and accordingly the law of electrical resistance was formulated, which is measured by a unit called an ohm, symbolized by omega <\/span><\/span>\u00a0\u03a9<\/span><\/span><\/strong> .<\/span><\/span><\/p>\n
