Common Electrical Symbols

This article shows many of the frequently used electrical symbols for drawing electrical diagrams.

Common electrical symbols. Electrical info basic electrical symbols. Each symbol in an electrical schematic has its purpose and is used to replace the need for what would otherwise be text heavy descriptions. It might look fairly simple to most but it actually stands for three phase open delta grounded at common point. A good example is the electrical symbol below.

Some of the more common electrical symbols such as contacts switches coils push buttons motors indicator lights transformers circuit breakers and fuses you may see on ladder diagrams. The basic electrical symbols are used to simplify the drafting and to help people understand the electrical drawing. Electrical symbols are standardized throughout the industry so it is easy to achieve the ability to interpret the meaning of the symbols. Electrical symbols virtually represent the components of electrical and electronic circuits.

Resistor iec potentiometer ieee adjustable resistor has 3 terminals. There are some standard symbols to represent the components in a circuits. Used for zero potential reference and electrical shock protection. There are several other electrical wiring symbols used in residential and commercial wiring but the above list of symbols are the important ones.

Connected to the chassis of the circuit. 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. Electrical symbols or electronic circuits are virtually represented by circuit diagrams. Resistor ieee resistor reduces the current flow.

This article gives some of the frequently used symbols for drawing the circuits. Though these standard symbols are simplified the function descriptions can make you understand clearly.
