Electrical Symbols, Electrical Diagram Symbols
Drawing electrical circuit diagrams, you will need to represent various electrical and electronic devices (such as batteries, wires, resistors, and transistors) as pictograms called electrical symbols.
Traditionally these symbols may vary from country to country, but today they are standardized internationally to a large extent.
How to create Electrical Diagram using ConceptDraw DIAGRAM. Depending on type of electrical diagram it require variations of Electrical Symbols set. Most of symbols located in the libraries of Electrical Engineering Solution - electrical diagram symbols from the Industrial Engineering Area at the ConceptDraw Solution Park.

It is easy to recreate any informational system structure using diagrams. There are three main components of any ER diagram: entity, attribute and relationship. Basing on these three components, one can define other, less used elements, such as weak entity or relationship, derived attribute, recursive relationship etc. This is the set of graphic elements of ERD Chen's notation. This ERD notation is used to represent an entity–relationship models. It involves the set of geometric forms: rectangles - depicting entities, ovals - representing attributes and diamonds depicting relationships assigned for first-class objects, that can have relationships and attributes of their own. Connections are displayed with arrowed lines. It is known that the Chen's ERD notation is used to show a detailed view of entities and relationships. ConceptDraw Entity-Relationship Diagram solution from the Software Development section of Solution Park provides the ability to create ERD of database structure for software development purposes using the Chen’s notation elements.Picture: Components of ER DiagramRelated Solution:Mechanical Engineering →
