In this post, we are going to learn about the difference between the open and the close circuit.
Firstly, I start from basic terms,
What is Open Circuit?
In Open Circuit, the electric current (charged particles) does not flow from an active energy source to the connected load or other components due to the incomplete path.
You are watching: What is the difference between and open and closed circuit?
If any components disconnect or break from the circuit, this circuit works as the open circuit. Sometimes, the open circuit shows like OFF condition or fault condition.
Example of Open Circuit:
Suppose we have connected DC supply battery with the connected bulb as load, resistance and switch.
When the switch is open, the electric current does not flow from the source (battery) to the desired load (light).
Thus, this circuit does not conduct the electricity and zero potential difference occurs between two terminal of open switch due to the incomplete the path.
In another case, when we connect insulators or insulating devices in an electric circuit, electricity does not flow even though the circuit path is complete.
Given below is the diagram with connect source, load and insulator.
Due to the insulator, the current does not pass in a circuit, and light does not glow.
It means that, sometimes, an insulator works as an open circuit.
What is Closed Circuit?
In a closed circuit, the electric current (charged particles) flows from an active energy source to the connected load or other components due to the closed-loop path.
For the closed circuit, we requireconducting materials or conductor (like copper) paththe active voltage source device (like a battery)complete path or circuit to flow the electric current
Example of Closed Circuit:
Suppose, DC voltage supply battery is connected with the light (like load) and closed switch. Due to closed switch, the circuit makes the complete path to flow electric current.
From the above diagram, you can see the bulb is glowing in the closed circuit.
Difference between Open Circuit and Close Circuit
In tubular form, I am comparing the basic points- open circuit vs closed circuit.

|01||Basic||An open circuit makes an incomplete path to flows the active energy from the source to load.||A closed-circuit makes a complete path to flows the active energy from source to load.|
|02||Electric Current(Link)||In an electrical open circuit, the current does not flow.||In an electric closed circuit, current flow from positive charge to the negative charge particles.|
|03||Symbol(Basic)||It is represented by ‘( )’ in an electric circuit.||It is represented by ‘( . )‘ in an electric circuit.|
|04||Potential Difference(Link)||In an electric circuit, the potential difference does not occur between the two terminals of an open circuit.||In an electric circuit, the potential difference occurs between the two terminals of the closed circuit.|
|05||Nature||The open-circuit can’t conduct electricity.||Closed-circuit conducts electricity with the help of connected active elements (like a battery, PV cell, etc).|
|06||State||This circuit works as an OFF state position.||This circuit works continuously ON state position.|
07. Open and Closed Circuit Diagram
Open Circuit: In an electric open circuit, no electrical connection occurs in between the source and load.
If any sides of the source or other components disconnect in an electric circuit, the current will not flow. That’s why the load will not be activated.
Closed Circuit: In closed circuit, closed loop path occurs with the connected source and the load.
For the electrical and electronic circuit working (open circuit and closed circuit), we need a switch to make (ON) and break (OFF) the circuit.
In a power system, circuit breaker and fuse perform the same switching (make and break the circuit) role by the manually and automatically at fault condition.
This is the explanation of the open and closed circuit with the block diagram.
