Standard circuit diagram symbols. The number is sometimes followed by a letter indicating that components are grouped or matched with each other e g. This article shows many of the frequently used electrical symbols for drawing electrical diagrams. Basics 8 aov elementary block diagram. In electronic circuits there are many electronic symbols that are used to represent or identify a basic electronic or electrical device.

Circuit symbols are used in circuit schematic diagrams which show how a circuit is connected together electrically. An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions such as wires batteries resistors and transistors in a schematic diagram of an electrical or electronic circuit these symbols are largely standardized internationally today but may vary from country to country or engineering discipline based on traditional conventions. Basics 7 4 16 kv 3 line diagram. There are some standard symbols to represent the components in a circuits.

There are many electrical and electronic schematic symbols are used to signify basic electronic or electrical device. This article gives some of the frequently used symbols for drawing the circuits.

Electrical symbols electronic circuit symbols of schematic diagram resistor capacitor inductor relay switch wire ground diode led transistor power. Basics 13 valve limit switch legend. The standard circuit component symbols and circuit symbols are important for circuit schematic diagrams. A reference designator unambiguously identifies a component within an electrical schematic or on a printed circuit board the reference designator usually consists of one or two letters followed by a number e g.

Most of the industrial standard circuit items can be changed in the appearance style and color according to the requirement. They are mostly used to draw a circuit diagram and are standardized internationally by the ieee standard ieee std 315 and the british standard bs 3939. Though these standard symbols are simplified the function descriptions can make you understand clearly.
