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.

Star Network Topology →

Nodes of any computer network are somehow organized in a hierarchy or a layout. Some of the common layouts like star network topology are more reliable and some like ring topology withstand high loads better. It is also important to distinguish logical topologies from physical. This diagram represents a typical view of the star network topology. The star network topology is one of the most frequently used network topologies in the majority of office and home networks. It is very popular because of its low cost and the easy maintenance. The plus of the star network topology is that if one computer on the local network is downed, this means that only the failed computer can not send or receive data. The other part of the network works normally. The minus of using star network topology is that all computers are connected to a single point-switch, or hub. Thus, if this equipment goes down, the whole local network comes down.Star Network Topology *

What Is Information Architecture →

What is information architecture? Information architecture (IA) is a broad and abstract term. At the most general sense the information architecture describes the structure of a system, how the different pieces of information are related at the system and represents their relationships. The information architecture term was introduced by Richard Saul Wurman in 1975 and now is commonly used in the context of websites and intranets, information structures and computer systems.

Building Drawing Software for Designing Plumbing →

Any building project must respond to some requirements. Moreover, finding a drawing software for developing a waste water plan is significant. Designing plumbing plans may be difficult in the beginning, but practice makes perfect. Layout of plumbing fixtures and, kitchen equipment a is a very important part of the home's interior design. If you do not want to find out suddenly the bath in your kitchen, or stove in your bathroom, you need to pay due attention to this plan. ConceptDraw Building Plans libraries give you a number of vector objects. Using them you can quickly and professionally sketch a plan of kitchen or bathroom in proper scale and with objects depicting your desired equipment. Then your contractor never will confuse a bath with a stove and a washing machine with a toilet and your house will be really a home of your dreams.Building Drawing Software for Designing Plumbing

Activity Network (PERT) Chart →

Activity Network and Project Evaluation and Review Technique, or PERT, charts are a way of documenting and analyzing the tasks in a project. This diagram is constructed as part of the process in creating a schedule of corrective actions. The Activity Network Chart (PERT) shows the logical connections and consequence of tasks to be performed. It displays the time period for problem solving and the implementation of all activities through the critical path.Activity Network (PERT) Chart *
