In electrical engineering there are many types of symbols used to notate devices. These include symbols for polarity, switches, diodes, and batteries.
No-one created circuit symbols; they evolved over time. And, in fact, different countries use different standards for their symbols so US standard symbols, for example, are different from European standards.
In electrical terms, a symbol represents a specific electrical component or function in circuit diagrams. These standardized graphical representations allow engineers and technicians to easily interpret and communicate circuit designs without ambiguity. Common symbols include those for resistors, capacitors, diodes, and switches, each conveying essential information about the component's characteristics and behavior in the circuit. Using symbols enhances clarity and efficiency in electrical schematics and documentation.

Operators are the symbols, which are used to perform different arithmetical and logical operations in BASIC.
Visual symbols are symbols that you see everyday in day life and you recognize and know its meaning right away.
Commonly used electrical symbols on blueprints include those for power sources, switches, outlets, lights, and various other electrical components. These symbols are standardized to represent different elements in electrical systems for clear communication and understanding among professionals in the field.
The National Electrical Code (NEC) does not specify a universal set of electrical drawing symbols for all cases. Instead, it provides guidelines and requirements for electrical installations, while the symbols used in electrical drawings can vary by region, standard, or organization. Different industries and local codes may adopt their own sets of symbols, so it's important to refer to the specific standards relevant to a project.
Electrical symbols are standardized representations used in circuit diagrams to illustrate various components and their functions. Common symbols include the battery (two parallel lines, one longer than the other), resistor (a zigzag line), capacitor (two parallel lines with a gap), and switch (a break in the line with a connecting arm). Additional symbols represent devices like diodes, transistors, and ground connections, each conveying specific electrical characteristics or behaviors. Understanding these symbols is essential for reading and interpreting electrical schematics effectively.

Electrical safety symbols warn of possible hazards. Information and explanation can be found online at websites such as Electrical Safety Forum and Wise Geek.
The symbols and abbreviations on electrical documents, such as schematics and wiring diagrams, represent various components, functions, and connections within an electrical system. Common symbols include resistors, capacitors, switches, and power sources, each with a standardized representation for clarity. Abbreviations often denote specific electrical terms, such as "AC" for alternating current or "DC" for direct current, helping streamline communication among engineers and technicians. Understanding these symbols is crucial for interpreting and troubleshooting electrical systems effectively.
Different societies have different reasons for having symbols, hence, the symbols are different. Tne symbols would be different, anyway, as different societies speak different languages, for the most part.
Different symbols were introduced by different people.
A number by itself is meaningless. Symbols and labels add meaning in math. Symbols in math are used to represent different operations, and/or add descriptions. There are many different symbols each which have their own purpose. Some symbols have different purposes in different types of math.
Scientists use symbols for diagrams of electrical circuits for a simple reason; to save space. The actuall names of the components would take up immense space on the diagram.
