How to Draw a Circuit Diagram
Part 1: What is Circuit Diagram?
Circuit diagrams illustrate how electrical circuits are composed. It will consist of electrical connections, power sources, switches, wire joints, etc.
Circuit diagrams are used by professionals to design, construct, and maintain circuits in rooms or structures. Students are also taught to use electrical diagrams to understand basic principles of power and electricity.
A circuit diagram's benefit lies in the fact that it acts as a universal guide about circuit. It is particularly practical for electrical maintenance professionals who need to understand and know exactly how the structure's circuits are laid out.
Part 2: 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.

Part 5: Circuit Diagram Examples
Example 1: DC Circuit
A DC circuit diagram in problems relating to Ohm’s Law. The most common configurations of a DC circuit are series; parallel; two loop, multiple source; voltage divider; combination, single source; and battery with internal resistance.
Example 2: AGC Circuit Diagram
This is an example of an Automatic Gain Control (AGC) circuit diagram. It is a closed-loop feedback regulating circuit used in an amplifier. It is most commonly seen in devices such as radio receivers and radar systems.
