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

Firstly, I begin from straightforward terms,

What is open Circuit?

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

You are watching: Difference between closed circuit and open circuit

If any kind of components disconnect or break from the circuit, this circuit functions as the open circuit. Sometimes, the open circuit shows like OFF condition or fault condition.

Example of open Circuit:

Suppose we have linked DC supply battery through the linked bulb together load, resistance and also switch.

When the switch is open, the electric current does not flow from the source (battery) to the preferred load (light).


Thus, this circuit does not conduct the electricity and zero potential distinction occurs in between two terminal of open up switch because of the incomplete the path.

In an additional case, as soon as we connect insulators or insulating gadgets in an electrical circuit, electrical energy does no flow even though the circuit path is complete.

Given listed below is the chart with attach source, load and also insulator.


Due to the insulator, the existing does not pass in a circuit, and also light does no glow.

It way that, sometimes, one insulator works as an open circuit.

What is closeup of the door Circuit?

In a closeup of the door circuit, the electric present (charged particles) operation from an energetic energy resource to the linked load or other materials due come the closed-loop path.

For the closed circuit, we need

conducting products or conductor (like copper) paththe active voltage source maker (like a battery)complete path or circuit to circulation the electric current

Example of closeup of the door Circuit:

Suppose, DC voltage supply battery is associated with the irradiate (like load) and closed switch. Due to closed switch, the circuit renders the complete path to flow electric current.


From the over diagram, you deserve to see the bulb is glow in the close up door circuit.

Difference in between Open Circuit and Close Circuit

In tubular form, i am compare the an easy points- open up circuit vs closeup of the door circuit.

#Content Open Circuit Closed Circuit
01BasicAn open up circuit renders an incomplete course to operation the energetic energy native the resource to load. A closed-circuit provides a finish path to operation the energetic energy from resource to load.
02Electric Current(Link)In an electric open circuit, the present does no flow.In an electric closed circuit, current flow from hopeful charge come the negative charge particles.
03Symbol(Basic)It is represented by ‘( )’ in an electric circuit.It is stood for by ‘( . )‘ in an electric circuit.
04Potential Difference(Link)In an electric circuit, the potential distinction does no occur in between the 2 terminals of an open circuit. In an electric circuit, the potential difference occurs between the 2 terminals the the close up door circuit.
05NatureThe open-circuit can’t conduct electricity.Closed-circuit conducts electricity with the assist of connected energetic elements (like a battery, PV cell, etc).
06StateThis circuit works as one OFF state position.This circuit works repeatedly ON state position.

07. Open and Closed Circuit Diagram

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


If any type of sides of the resource or other contents disconnect in an electrical circuit, the present will not flow. That’s why the pack will no be activated.

Closed Circuit: In closed circuit, closeup of the door loop course occurs through the connected resource and the load.


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

In a strength system, circuit breaker and fuse perform the same switching (make and also break the circuit) duty by the manually and automatically at error condition.

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