In this post, we room going to learn around the difference between the open and also the close circuit.

Firstly, I begin from basic terms,

What is open Circuit?

In open Circuit, the electric present (charged particles) walk not flow from an energetic energy resource to the linked load or other materials due come the incomplete path.

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

If any components disconnect or rest from the circuit, this circuit functions as the open up circuit. Sometimes, the open circuit shows favor OFF problem or error condition.

Example of open Circuit:

Suppose us have associated DC supply battery v the linked bulb together load, resistance and also switch.

When the switch is open, the electric existing does not circulation from the resource (battery) come the preferred load (light).


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

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

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


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

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

What is closed Circuit?

In a closeup of the door circuit, the electric current (charged particles) flows from an energetic energy resource to the connected load or other contents due to the closed-loop path.

For the closed circuit, we need

conducting materials or conductor (like copper) paththe energetic voltage source device (like a battery)complete course or circuit to flow the electric current

Example of closed Circuit:

Suppose, DC voltage it is provided battery is linked with the irradiate (like load) and also closed switch. Due to closed switch, the circuit renders the complete path to flow electrical current.


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

Difference between Open Circuit and also Close Circuit

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

#Content Open Circuit Closed Circuit
01BasicAn open circuit renders an incomplete route to flows the energetic energy native the resource to load. A closed-circuit renders a finish path to operation the active energy from resource to load.
02Electric Current(Link)In an electrical open circuit, the existing does no flow.In an electrical closed circuit, current flow from confident charge come the negative charge particles.
03Symbol(Basic)It is represented by ‘( )’ in an electrical circuit.It is represented by ‘( . )‘ in an electric circuit.
04Potential Difference(Link)In an electric circuit, the potential distinction does no occur between the two terminals the an open up circuit. In an electric circuit, the potential distinction occurs between the two terminals that the close up door circuit.
05NatureThe open-circuit can’t conduct electricity.Closed-circuit conducts electrical power with the aid 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 electric open circuit, no electrical connection occurs in in between the resource and load.


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

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


For the electrical and also electronic circuit functioning (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 carry out the exact same switching (make and also break the circuit) function by the manually and automatically at error condition.

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