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

Firstly, I start from basic terms,

What is open up Circuit?

In open Circuit, the electric existing (charged particles) does not flow from an energetic energy resource to the connected load or other components due come the incomplete path.

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

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

Example of open up Circuit:

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

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


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

In one more case, as soon as we connect insulators or insulating gadgets in an electrical circuit, electricity does no flow also though the circuit route is complete.

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


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

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

What is closed Circuit?

In a closeup of the door circuit, the electric present (charged particles) flows from an energetic energy resource to the linked load or other materials due to 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 electrical current

Example of closed Circuit:

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


From the over diagram, you have the right to see the pear is glowing 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 closed circuit.

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

07. Open and Closed Circuit Diagram

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


If any kind of sides the the resource or other materials disconnect in an electric circuit, the existing will not flow. That’s why the pack will not be activated.

Closed Circuit: In closed circuit, close up door loop path occurs v the connected source and the load.


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

In a power system, circuit breaker and also fuse perform the very 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 with the block diagram.
