Get a grasp the meaning behind each symbol in a circuit diagram with the help of these diagrams. There are common symbols available in a circuit diagram these symbols are 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. Check out our **Circuit Diagram Symbols **guide below and start learning the name and function of each symbol.

These *Circuit Diagram Symbols* include the charts of the common engineering symbols in a circuit and schematic diagrams and what they represent. Circuit diagrams are the pictures with symbols that have internationally standardized. Circuit diagrams show the connections as clearly as possible with all wires drawn neatly as straight lines. A single cell or other power source is represented by a long and a short parallel line. A collection of cells or battery is represented by a collection of long and short parallel lines. A straight line is used to represent a connecting wire between any two components of the circuit.

Resistors on a schematic are usually represented by a few zigzag lines, with two terminals extending outward. Schematics using international symbols may instead use a featureless rectangle, instead of the squiggles. Meanwhile, circuit symbols are used in circuit diagrams showing how a circuit is connected together. The most fundamental of circuit components and symbols are also provided in the following charts!
