# What Do The Symbols On An Electrical Schematic Represent

What do the symbols on an electrical schematic represent? Electrical schematics are a type of diagram that shows the electrical components of a circuit and how they are connected. They are used by electrical engineers and technicians to design, build, and troubleshoot electrical systems.

The symbols on an electrical schematic are standardized, so that they can be understood by people all over the world. This standardization is maintained by the International Electrotechnical Commission (IEC).

The most common electrical schematic symbols are for resistors, capacitors, inductors, diodes, transistors, and integrated circuits. These symbols are typically represented by a simple geometric shape, with additional lines and markings to indicate the component's properties.

For example, a resistor is represented by a zig-zag line, while a capacitor is represented by two parallel lines with a line between them. A diode is represented by a triangle with a line through it, and a transistor is represented by a circle with three terminals.

In addition to the basic electrical components, there are also symbols for switches, relays, transformers, and other electrical devices. These symbols are typically more complex than the basic component symbols, and they may include additional information such as the device's voltage rating or current rating.

Electrical schematics are an essential tool for anyone who works with electrical systems. They can be used to visualize the design of a circuit, to troubleshoot problems, and to make repairs. By understanding the symbols on an electrical schematic, you can gain a deeper understanding of how electrical systems work.

Here is a table of some of the most common electrical schematic symbols: | Symbol | Component | Description | |---|---|---| | | Resistor | A device that opposes the flow of current | | | Capacitor | A device that stores electrical energy | | | Inductor | A device that creates a magnetic field when current flows through it | | | Diode | A device that allows current to flow in one direction only | | | Transistor | A device that controls the flow of current | | | Integrated Circuit | A small chip that contains many electronic components | | | Switch | A device that connects or disconnects an electrical circuit | | | Relay | A device that uses an electromagnet to switch an electrical circuit | | | Transformer | A device that changes the voltage or current of an electrical circuit |
