What are the actions of an electrical circuit if the circuit is found open?

Electrons cannot traverse or move thru an open circuit. Therefore there is no current or 'electron' flow. Voltage may be present with an open circuit but it is doing no 'work'.
Compare an open circuit with 'potential' energy. Even though potential energy exist there is no kinetic energy unless the electrons have a path to take.
An open circuit provides no such path.
Kinetic energy means something with mass is moving and in some cases that movement is harnessed to accomplish 'work'.
Potential (voltage) which is doing nothing because a circuit is open cannot accomplish any work since there are no electrons moving.
Another perspective:
If an electric circuit is opened, the electricity flow stops. This is due to the fact that air is a strong insulator, and most amounts of electricity (save for lightning) do not have enough voltage to overcome this resistance (in a process called ionization). This is reflected in a formula V = I × R where r is resistance, i is amperage, and v is voltage. Through this relationship, as resistance reaches a high level, voltage drops, and the electric flow stops because it cannot overcome the resistance with the force of voltage or amps.
A thought on the ionization process:
As ionization occurs, resistance across the 'gap path' drops and voltage, if not regulated will drop as well. When there is not enough voltage to cause ionization the voltage will be higher than at the time ionization occurs.
At ionization, current (I) will increase, resistance (R) will decrease and voltage (E) will decrease as well and the potential (voltage) is now causing energy or electrons to flow.
As the ionization occurs much less voltage or potential is required to maintain the ionization path than is required to achieve ionization to start with.
Example: A cars ignition coil is capable of producing 45K~50K volts of electricity.
Yet when the voltage is measure at the end of the spark plug wire there will be only 9K or 10K volts due to the air/fuel molecules being ionized
Not to sure ionization actually is applicable to the original question however. :0)
BTW, I'm 'old school' where E=I x R where E = Voltage.
Just like megacycles to megahertz, I guess everything changes but the laws of physics.

∙ 14y agoThere is no current in an open circuit.
To you in St. Louis mo. that is my one student answer for the day.

Does an open circuit have a break that interrupts the flow of electrical charges?
Of course it has a break . open circuit means infinite resistance , so no electrical charge can flow through it .
What does a circuit breaker do in a circuit?
Creates an open circuit in the event that the circuit becomes overloaded. It's a protection feature, preventing melting wires, damage to electrical components, and fires.
Is an open switch in an electrical circuit to prevent current flow?
Yes, an open switch breaks the circuit and prevents electricity flowing through. A closed switch on the other hand completes the circuit and in turn helps electricity travel through the circuit.
What is the difference between an open circuit and an open aev?
This is copied from Section 6.11, Question 8 in "Modern Refrigeration and Air Conditioning." The answer is (B), "The open circuit prevents flow. The open AEV allows flow to occur." Although a bit obscure, the answer is correct because, within the context of an electrical circuit, an "open circuit" (i.e. disconnected wire) would prevent the flow of electrical current. Within the context of a refrigeration circuit, an open AEV (automatic expansion valve) would permit the flow of refrigerant into an evaporator coil to provide cooling.
How do you find shorts and opens in an electrical circuit in multimeter?
An open circuit essentially has an infinite resistance. It is shown on digital multimeter as OL. (Open Line) A short circuit should read zero, or nearly zero, depending on the accuracy of the meter.
If an electrical circuit is not complete it is said to be?
An open circuit
When you turn on a television what is the electrical circuit?
The electrical circuit when turned on it is considered closed. By the same token when an electrical circuit is turned off the electrical circuit is considered open.
What are the kind of circuit?
the electrical circuit, load, conductor, open circuit, switch,
What is an electrical path that is not complete?
open circuit
When electrical circuit is open?
An open electrical circuit means that no electricity is flowing through the circuit. This could be because a switch is in the off position, or there is a break in the wiring, or a component in the circuit has failed, and other reasons are possible.
What is a break in an electrical circuit called?
A break in an electric circuit is called an open circuit. Electric current will not flow through an open circuit.
Will an electrical current move through an open circuit or a closed circuit?
electricity
Does an open circuit have a break that interrupts the flow of electrical charges?
Of course it has a break . open circuit means infinite resistance , so no electrical charge can flow through it .
What device will open or close the break in a electrical circuit?
A switch.
What is a breaker and what is it used for?
An electrical breaker is a safety device used to open a circuit that has an electrical fault on it.
What is an electrical tool that melts to open a circuit if an electrical current gets too high?
fuse
What is open circuit and short circuit?
Consider two points (A and B) in an electric circuit. An open circuit between A and B means there is no electrical connection between A and B. A short circuit between A and B means there is an electrical connection between A and B.
