In this post, we space going come learn around the difference in between the open and the near circuit.

Firstly, I begin from simple terms,

What is open up Circuit?

In open up Circuit, the electric current (charged particles) go not flow from an active energy source to the linked load or other materials due to the incomplete path.

You are watching: What is the difference between a closed and open circuit

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

Example of open Circuit:

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

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


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

In one more case, once we attach insulators or insulating gadgets in an electric circuit, electrical power does not flow even though the circuit route is complete.

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


Due come the insulator, the present does not pass in a circuit, and light does no glow.

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

What is closeup of the door Circuit?

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

For the close up door circuit, we require

conducting products or conductor (like copper) paththe active voltage source machine (like a battery)complete course or circuit to flow the electric current

Example of closeup of the door Circuit:

Suppose, DC voltage it is provided battery is associated with the irradiate (like load) and also closed switch. Because of closed switch, the circuit makes the complete path to flow electrical current.


From the over diagram, you can see the pear is glow in the closeup of the door circuit.

Difference between Open Circuit and Close Circuit

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

#Content Open Circuit Closed Circuit
01BasicAn open circuit makes an incomplete path to operation the energetic energy from the resource to load. A closed-circuit makes a complete path to flows the active energy from resource to load.
02Electric Current(Link)In an electrical open circuit, the present does not flow.In an electrical closed circuit, current flow from hopeful charge come the an unfavorable 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 electrical circuit, the potential difference does no occur in between the 2 terminals that an open circuit. In an electric circuit, the potential distinction occurs between the 2 terminals the the closed circuit.
05NatureThe open-circuit can’t conduct electricity.Closed-circuit conducts power with the aid of connected energetic elements (like a battery, PV cell, etc).
06StateThis circuit works as an OFF state position.This circuit works repetitively ON state position.

07. Open and also Closed Circuit Diagram

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


If any type of sides that the source or other components disconnect in an electrical circuit, the existing will not flow. That’s why the pack will not be activated.

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


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

In a power system, circuit breaker and fuse carry out the exact same switching (make and also break the circuit) function by the manually and also automatically at error condition.

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