Electrical Symbols, Electrical Diagram Symbols
When drawing Electrical Schematics, Electrical Circuit Diagrams, Power Systems Diagrams, Circuit and Wiring Diagrams, Digital and Analog Logic Schemes, you will obligatory need the electrical symbols and pictograms to represent various electrical and electronic devices, such as resistors, wires, transistors, inductors, batteries, switches, lamps, readouts, amplifiers, repeaters, relays, transmission paths, semiconductors, generators, and many more. Today these symbols are internationally standardized, so the diagrams designed using them are recognizable and comprehensible by specialists from different countries. Electrical Engineering Solution included to ConceptDraw Solution Park provides 26 libraries with 926 commonly used electrical schematic and electrical engineering symbols making the reality the easy drawing of Electrical diagrams, schematics and blueprints. Now you need only a few minutes to create great-looking Electrical diagram, simply choose required electrical design elements from the libraries, drag them on the needed places at the document and connect in a suitable way.Electrical Symbols — Qualifying
A qualifying symbol is graphics or text added to the basic outline of a device’s logic symbol to describe the physical or logical characteristics of the device. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram."In electronics, a vacuum tube, electron tube (in North America), tube, or thermionic valve or valve (in British English) is a device controlling electric current through a vacuum in a sealed container. The simplest vacuum tube, the diode, contains only two elements; current can only flow in one direction through the device between the two electrodes, as electrons emitted by the hot cathode travel through the tube and are collected by the anode. Addition of a third and additional electrodes allows the current flowing between cathode and anode to be controlled in various ways. The device can be used as an electronic amplifier, a rectifier, an electronically controlled switch, an oscillator, and for other purposes.
Vacuum tubes mostly rely on thermionic emission of electrons from a hot filament or a cathode heated by the filament. Some electron tube devices rely on the properties of a discharge through an ionized gas." [Vacuum tube. Wikipedia]
"The EL34 is a thermionic valve or vacuum tube of the power pentode type. It has an international octal base (indicated by the '3' in the part number) and is found mainly in the final output stages of audio amplification circuits and was designed to be suitable as a series regulator by virtue of its high permissible voltage between heater and cathode and other parameters. The American RETMA tube designation number for this tube is 6CA7. Russian analog is 6P27S (Cyrillic: 6П27C )" [EL34. Wikipedia]

Business Diagram Software
When managing the projects, people, or networks, there are daily designed and used different types of Business diagrams, so the powerful drawing software will be very useful for this. ConceptDraw DIAGRAM with large quantity of business solutions will meet your needs and will help you convey your ideas successful and rapidly, no matter are you professional or beginner. It is the best choice for business specialists and technical professionals who need quickly and easily explore, visualize, and communicate information. ConceptDraw DIAGRAM business diagram software is the most powerful business software and relational charting software. Create advanced, completely customizable Business Process Diagrams, Business Flow Charts, Work Flow Diagrams, Organizational Charts, Audit diagrams, Marketing diagrams, Value Stream Maps, TQM diagrams, ERD diagrams, EPC diagrams, Cause and Effect diagrams, Infographics, Dashboards, and other Relational business diagrams from your data using the powerful drawing tools of ConceptDraw Solution Park.Business Process Workflow Diagram
Business Process Workflow Diagram is a professional visual tool that is widely applied for business development, business analysis, business process optimization and documenting business processes. Business Process Workflow Diagram lets depict in details the steps of business processes and flow of tasks between them, the execution of business processes, transfer of data and documents. The workflows on the Business Process Workflow Diagram are represented using the set of common symbols which let easy illustrate business processes and process flows, depict the start, all major steps and end of the process, what data are used by the process, how the data flow through the business areas within scope of our project, how the tasks are executed and by who, and how workers interact with each other.Entity Relationship Software
Entity Relationship Diagram (ERD) is a leading data modeling tool that is used to illustrate the logical structure of database, helps to organize and represent your project's data in terms of entities, attributes and relationships. To describe the database structure usually is used the ERD Chen's or Crow's Foot notation. Chen's notation supposes the representation of entities by rectangles with the entities names inside, relationships by diamonds and attributes by ovals connected with a line to exactly one entity. In Crow's Foot notation the boxes are used to depict the entities and their attributes, the lines between them - to depict relationships. ConceptDraw DIAGRAM software extended with Entity-Relationship Diagram (ERD) Solution is convenient and useful for designing the ER Diagrams, and supports the use of Chen's or Crow’s Foot notation according to your needs and desires. The ERD diagrams produced with ConceptDraw DIAGRAM Entity Relationship Diagram software can be successfully used in whitepapers, presentations, posters, datasheets, technical materials, etc.- Symbol Of Potential Transformer In Sld
