In this article we will see the basic schematic symbols in general. Circuit layouts and schematic diagrams are a simple and effective way to illustrate the electrical connections, components, and operation of a particular electrical circuit or system. Basic electrical and electronic graphic symbols, called Schematic Symbols, are widely used in circuit diagrams, diagrams and computer-aided drawing packages to define the position of individual components and elements within a circuit.
Graphic symbols define not only the position of a component, but also the type of electrical element such as resistant, inductive, capacitive, mechanical, etc. Thus, in circuit diagrams and diagrams, graphic symbols identify and represent electrical and electronic devices and show how they are electrically. represents wires or component ends when drawing lines between them when connecting to each other.
The anchor ends or pins of a component in a schematic diagram can be defined using letters or abbreviations. For example, the connectors of a bipolar connection transistor (BJT) are defined as E (emitter), B (base), and C (collector). Arrows are also used in schematic symbols to indicate the direction of the transformational current flow around or through a circuit, or as part of graphical symbols to indicate that components have a variable or adjustable value. For example, a pocinciometer or reostat.
Although electrical components are represented by universally accepted schematic symbols, there are a number of variants and alternative symbols used worldwide to represent the same electrical component or device. For example, the IEC (International Electrotechnical Commission) has a symbol set, while the IEEE (Institute of Electrical and Electronics Engineers) has an alternative set of symbols for the same component.
The main electrical and electronic graphic symbols presented here are more generally accepted graphic symbols due to their widespread use in various electrical and electronic fields. The following individual graphic symbols are provided with a brief description and description.
