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.

Interior Design →

Working as a designer, you might find developing projects exciting and difficult at the same time. It is a challenging task to create a usable interior design that will fulfill all the customer’s requirements. So, in order to aid yourself, you can use special software to create site plans, landscape designs, furniture layouts. This example of an interior plan introduces an internal area of a small cafe. The floor plan demonstrates interior angle "view from above". It involves many different elements of furniture such as tables , chairs and various cushioned furniture. Also it includes a kitchen fixtures and furniture. Making this plan was managed by the ConceptDraw Cafe and Restaurant Floor Plan solution. The libraries, composing this solution contain about vector graphic 300 objects. It can be use to help interior designers to develop interior design proposals, communicate ideas and concepts that relate to a interior design.Interior Design *

Types of Flowchart - Overview →

A flowchart is a powerful tool for examining processes. It helps improving processes a lot, as it becomes much easier to communicate between involved people, to identify potential problems and to optimize workflow. There are flowcharts of different shapes, sizes and types of flowchart vary from quite basic process flowcharts to complex program flowcharts. Nevertheless, all these diagrams use the same set of special symbols like arrows to connect blocks, parallelogram to show data receiving or rectangles for showing process steps. Basic flowcharts are used to represent a simple process algorithm. A basic flowchart notation consists of rectangles (business processes), arrows (the flow of information, documents, etc.). The same notation is used in items such as the "decision", which allow you to do the branching. To indicate the start of the entire business process and its termination can be used the "Terminator" element. The advantages of Basic Flowchart are simplicity and clarity. With it you can quickly describe the business process steps. Creating of Basic Flowchart does not require any special knowledge, as easily understand by employees with different levels of education and IQ.Types of Flowchart - Overview *
