Electrical Symbols — Electrical Circuits

A circuit diagram or wiring diagram uses symbols to represent parts of a circuit. Electrical and electronic circuits can be complicated. Making a drawing of the connections to all the component parts in the circuit's load makes it easier to understand how circuit components are connected. Drawings for electronic circuits are called "circuit diagrams". Drawings for electrical circuits are called "wiring diagrams".

A schematic is a diagram of an electrical circuit. A schematic doesn't look like a life like a circuit, but it does show the essential connections. Schematics use symbols to represent components in the circuit. We use conventions in a schematic, we use them to represent the way electricity flows. The common convention we use is from the positive to the negative terminal. The realistic way electricity is from the negative to the positive terminal.

How to Create an Schematic of Circuit Using Electrical Circuits Library

  • Open ConceptDraw DIAGRAM new document page.
  • Select libraries from Electrical Engineering section.

    Libraries from Electrical Engineering section

  • Electrical circuits library contains objects, identified by a blue tile in the library pane. Such objects can be edited by using the Action button menu. To open the menu select an object and click the Action Button button in the upper right corner of the object. Action button menu
  • Select the Smart Connector tool Smart Connector. To connect elements using this tool, drag the connector from one connect dot to another.You can use Layers to place connections on different layers.
  • Result: Schematic of Circuit.

Local area network (LAN). Computer and Network Examples →

Computer networks nowadays are spread all across the world. The large number of parameters, such as geographic scale or communication protocols, can divide networks. One of the most common types of networks is called local area network (LAN). It convenient to represent network examples by means of diagrams. This local area network (LAN) diagram provides an easy way to see the way the devices in a local network are interacted. The diagram uses a library containing specific symbols to represent network equipment , media and the end-user devices such as computers (PC, mac, laptop) , network printer, hubs, server and finally a modem. There are two types of network topologies: physical and logical. The current diagram represents precisely a physical type of LAN topology because it refers to the physical layout of a local network equipment.Local area network (LAN) diagram

Circuits and Logic Diagram Software →

A circuit diagram is sometimes also called an elementary diagram, electronic schematic or electrical diagram circuits. It is essential in construction of any electronic equipment. Among many digital drawing tools available, ConceptDraw DIAGRAM is a leading circuits and logic diagram software, affording for easy and quick creation of even the most advanced and complex diagram designs. This makes it a perfect choice for computer science and any kind of electronic engineering. This drawing includes the graphic symbols that may be in use while creating a logic circuit diagram. The diagrams of such kind are used in the electronics industry. The logic symbol depicts a device that realizes a Boolean type functions. Practically a logic symbol means transistor, diodes, relays, and other mechanical or optical details which provide function of closing or opening "gates". Totally the logic circuits can involve millions of gates. ConceptDraw Electrical Engineering solution gives the opportunity to create a circuit diagrams both simple and difficult.Circuits and Logic Diagram Software *

Material Requisition Flowchart. Flowchart Examples →

A requisition form is one of the documents used for accounting in different manufacturing processes. There are two main types of requisition: a purchasing requisition and material requisition and difference between them is significant. Creating a flowchart might help you in understanding all the details of accounting process. Flowcharts are a best visual method for dividing a large and complicated procedure into a several little clear pieces. The main value-ability of an effective flowchart is its simpleness. Material requisition flowcharts are used to document the process of relationships between the different departments and the purchasing department within an organization. The flow chart gives the step-by-step guide on how is carried out the procurement process of the materials necessary for the functioning of the organization. This type of flowchart along with many other business flowcharts, one can easy create using ConceptDraw Flowcharts solution.Material Requisition Flowchart. <br>Flowchart Examples *

Types of Flowcharts →

A flowchart is a simple but very functional tool when it comes to understanding a workflow or to removing unnecessary stages from a process. When drawing flowcharts, keep in mind that there are four common types of flowcharts, like document flowcharts and data flowcharts that show control over a data or document flow over a system. To show controls on a physical level, use system flowcharts. In addition, to show controls in a program, you can draw a program flowchart. This flowchart diagram represents the piece of an article editing process, that involves the author and editor. It was created using the Basic Flowchart notation that consists from the basic flowchart symbols. The start and the end of the process are indicated with "Terminator" symbols. The "Process" symbols show the action steps consisting from making edits and searching for a compromise, when the author does not agree with the suggestions of the editor. The "Process" symbol is the general symbol in process flowcharts. The "Decision" symbol indicates a branching in the process flow. There are two branches indicated by a Decision shape in the current flowchart (Yes/No, Disagree/Agree). This basic flowchart can be used as a repeating unit in the workflow diagram describing the working process of some editorial office.Types of Flowcharts *
