In this post, we are going to learn about the difference between the open and also the near circuit.

Firstly, I start from an easy terms,

What is open up Circuit?

In open up Circuit, the electric current (charged particles) does not circulation from an energetic energy resource to the connected load or other materials due to the incomplete path.

You are watching: That which can open or close a circuit

If any components disconnect or rest from the circuit, this circuit works as the open circuit. Sometimes, the open up circuit shows choose OFF problem or fault condition.

Example of open Circuit:

Suppose us have linked DC it is provided battery through the connected bulb together load, resistance and also switch.

When the switch is open, the electric present does not circulation from the resource (battery) to the desired load (light).


Thus, this circuit does no conduct the electricity and zero potential difference occurs in between two terminal of open switch because of the incomplete the path.

In an additional case, once we attach insulators or insulating gadgets in an electrical circuit, electrical power does not flow also though the circuit path is complete.

Given listed below is the diagram with connect source, load and insulator.


Due to the insulator, the existing does not pass in a circuit, and light does not glow.

It way that, sometimes, an insulator functions as an open up circuit.

What is closeup of the door Circuit?

In a close up door circuit, the electric existing (charged particles) operation from an active energy resource to the linked load or other components due come the closed-loop path.

For the close up door circuit, we call for

conducting materials or conductor (like copper) paththe active voltage source device (like a battery)complete route or circuit to circulation the electrical current

Example of close up door Circuit:

Suppose, DC voltage supply battery is linked with the light (like load) and closed switch. Because of closed switch, the circuit provides the complete path come flow electric current.


From the above diagram, you deserve to see the pear is glowing in the close up door circuit.

Difference in between Open Circuit and Close Circuit

In tubular form, ns am to compare the simple points- open up circuit vs close up door circuit.

#Content Open Circuit Closed Circuit
01BasicAn open circuit makes an incomplete route to flows the active energy indigenous the resource to load. A closed-circuit makes a complete path to operation the energetic energy from source to load.
02Electric Current(Link)In an electric open circuit, the existing does not flow.In an electric closed circuit, present flow from positive charge to the negative charge particles.
03Symbol(Basic)It is represented by ‘( )’ in an electric circuit.It is stood for by ‘( . )‘ in an electrical circuit.
04Potential Difference(Link)In an electric circuit, the potential distinction does no occur in between the two terminals that an open up circuit. In an electrical circuit, the potential distinction occurs between the 2 terminals of the closed circuit.
05NatureThe open-circuit can’t command electricity.Closed-circuit conducts electrical energy with the help of connected active elements (like a battery, PV cell, etc).
06StateThis circuit functions as an OFF state position.This circuit works consistently ON state position.

07. Open and also Closed Circuit Diagram

Open Circuit: In an electrical open circuit, no electrical connection occurs in in between the source and load.


If any type of sides the the source or other materials disconnect in an electrical circuit, the current will not flow. That’s why the fill will not be activated.

Closed Circuit: In closeup of the door circuit, close up door loop path occurs with the connected source and the load.


For the electrical and also electronic circuit working (open circuit and closed circuit), we need a switch to do (ON) and break (OFF) the circuit.

In a strength system, circuit breaker and also fuse do the very same switching (make and also break the circuit) role by the manually and also automatically at fault condition.

This is the explanation of the open and closed circuit through the block diagram.
