Want to draw a circuit diagram? This article will provide you with a detailed introduction to the circuit diagram and show you how to make a circuit diagram with Edraw circuit diagram software.

What is a Circuit Diagram?

The Circuit Diagram is a kind of graphical representation of an electrical circuit, showing how electrical components are connected together. It's usually used by engineers and electricians to explain elements and paths of an electrical circuit, which is important in design, construction, and maintenance of electrical and electronic equipments.

Standard Circuit Symbols for Designing

Circuit diagrams use international standard symbols to provide schematic diagrams of the circuit and its components. Each symbol is intended to represent some features of the physical construction of the device. First, you need to identify the symbols used to represent the components you wish to draw. Edraw provides you with hundreds of circuits symbols including cell, battery, source, resister, switch, lamp, motor, bell, buzzer, relay, capacitor, etc.

Below are some frequently used circuits symbols:

Frequently Used Circuits Symbols

  • Cell: A cell stands for electrical energy supply. A single cell is often called a battery, but strictly a battery is two or more cells joined together. It's represented by a long and a short parallel line.
  • Battery: A battery is more than one cell. The larger terminal (on the left) is positive (+).It is represented by a collection of long and short parallel lines.
  • Wire: Pass current from one part of the circuit to another. It's a connecting wire between two components.
  • Resister: A resister is used to restrict the flow of a current. It's represented by a zigzag line.
  • Switch: An on-off switch allows current to flow only when it is in the closed (on) position. It's generally represented by providing a break in a straight line by lifting a portion of the line upward at a diagonal.
  • Ammeter: An ammeter is used to measure current. It's represented by a letter A in a circle.
  • Voltmeter: A voltmeter is used to measure voltage. It's represented by a letter V in a circle.
  • Motor: A transducer converts electrical energy to kinetic energy. It's represented by a letter M in a circle.
  • Lamp: A transducer which converts electrical energy to light.

In Edraw, numerous circuits symbols are embedded. Go to Standard Circuit Symbols page for a general knowledge about circuits symbols. Click Standard Electrical Symbols to study detailed function of each symbol.
