The circuit diagram represents the components and the flow of the power supply inside a device. Every circuit diagram represents a different device and its application. A closed-circuit diagram is through which current can flow in an uninterrupted path. For example, a television system in which the signal is usually sent by cable to a limited number of receivers has a closed circuit. To secure the flow of current, the path must be flawless. If there is a break anywhere in the path, the current flow stops, and the metallic atoms present in the wire settle to electrical neutrality. Let's understand more about it through the closed circuit diagram.

1. Understanding Closed Circuit Diagram

In the closed-circuit diagram, the circuit is closed, and it is composed of a conducting material that allows current to pass through it. The circuit closes when the switch is ON or when the key is added. Current flow through the circuit requires a closed path. If the path is open, the current flow does not happen. As the name denotes, they are closed, which ensures the current flow throughout the device or the circuit. And the output, the bulb, glows as there is current flow. The wires are internally connected in a closed circuit, and the current flow happens.

Battery - It supplies the power to the complete system.
Capacitor - In a circuit, the capacitor acts as a reservoir of electricity for the motor. It also serves the purpose of creating a poly-phase power supply from a single-phase power supply.
Resistor - In a circuit, the resistor serves to absorb returned energy and prevent the breakage of the circuit or system.

Choose a template
EdrawMax Online comes with hundreds of free diagram templates. Select a pre-designed template by entering the Keyword in the "Search" section or exploring different diagram sets. In this case, you will find different types of Electrical Circuits diagrams under the "Electrical Engineering" section under the "Engineering" section. You will find different diagram sets, like Basic Electrical, Circuits and Logic, Industrial Control System, and Systems' Diagram. Alternatively, you can simply click on "+" in EdrawMax Online canvas to create a diagram of your preference.

Work on your research
As per the Closed Circuit Diagram below, a closed circuit has a complete path for current to flow, whereas an open circuit doesn't, which means it's not functional. Furthermore, a closed-circuit allows electricity to flow from the (+) power to the (-) ground uninterrupted.

Customize the diagram
Customize your Closed Circuit diagrams by changing the color or adding more relevant data. Based on your research, you can also add or remove the Electrical Circuit symbols or content accordingly. Since it is about electrical engineering research, you can add more relevant data about different circuit diagrams.

Export & Share
Once your required circuit diagram is completed, you can share it amongst your colleagues or clients using the easy export and share option. You can further export the diagram in multiple formats, like Graphics, JPEG, PDF, or HTML. Also, you can share the designs on different social media platforms, like Facebook, Twitter, LinkedIn, or Line. In simple words, you can export your incredible Closed Circuit diagrams to the files you want with just a few clicks.

3. Important Tips to Consider While Creating Closed Circuit Diagram

Creating a closed circuit diagram is much easier than you think. It becomes easy if you understand the steps and the process involved. While designing this circuit, you may consider certain tips. Here are the tips in detail.

Always make sure to connect the circuit to the ground to avoid breakages and damages.
Check whether the switch is closed or open in the circuit as it differentiates the closed circuit from the open circuit.
Mark the value of each component used in the circuit.
Use separate colors for connections wherever needed to aid users in understanding the connection.
Always mention the result at the output terminal in this circuit diagram.


A simple light switch opens and closes the circuit that connects the light to a power source. In a closed circuit diagram, the electric current flows from an active energy source to the connected load or other components due to the closed-loop path. It is recommended to use EdrawMax Online to create Closed-circuit diagrams for your projects. It should be noted here that since these circuit diagrams are the blueprints of the actual working models, ensure that you use the correct symbols provided by EdrawMax Online.
