An open circuit does not work. You need to have a complete circuit for the electrical current to flow back to its source. For example: An open circuit occurs when a series fuse blows or a connector is unplugged.

∙ 10y agoA circuit can be opened by two methods, manual and automatic. The manual method is when a switch is in the circuit and it is manually shut off to open the circuit. The automatic method is when a fuse or breaker is in the circuit and it opens the circuit automatically when a fault current is sensed within the protected circuit.

If an electrical circuit is not complete it is said to be?
An open circuit
What would happen to circuit if there was no resistance?
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
What are the safety features available in a breaker?
To detect and open the circuit if a thermal overload is present and to detect and open the circuit if a short circuit caused by a magnetic increase of flux in the circuit.
Why is it necessary for oscillation to occur in a circuit?
It is not "necessary" for oscillation to occur in any "arbitrary" circuit. It depends on the design objectives. Please be more specific, and restate the question.
What instrument would you use to test for an open circuit?
The general answer is that a continuity tester is used to check for an open circuit.
What happens when the circuit is complete and the switches are closed?
*Look at the simple circuit illustrated in Figure A-2. What will happen when only switch S1 is closed? Correct Answer= "Nothing will happen-the light bulb won't light up." <<>> If there is a load in the circuit the load will operate. If there is no load in the circuit and it is complete then a short circuit will occur and something in the circuit will burn open. If the circuit is complete and there is a fuse or breaker in the circuit, then the fuse or breaker will open the circuit.
Why is an open circuit called open?
An open circuit is called open because the circuit has an opening, a disconnection. In other words, there is an open space in the circuit in which the electrons cannot move through.
What do you call a circuit when the switch is open?
An open 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.
What is the symbol for a open circuit?
When a circuit is in off condition then it is called an open circuit..
A wire wrapped around a magnet is an example of a open circuit?
No. An open circuit is any CIRCUIT (from circle) which is not closed. That is; any break in the circle (circuit) makes it an open circuit.
What is open circuit voltage when load is connected?
As load is conected in circuit , so thre is no open circuit therefore there would not be any open circuit voltage.
Is tram close circuit or open circuit?
If the circuit was open, the tram's motor could not run!
What is through a discontinuous circuit which no current can flow?
meaning that the current from your power source doesn't return to the positive end (electricity flows from - negative, to + positive)
What is the difference in an open circuit and a short circuit?
an open circuit is a circuit that does not complete the circle. an open circuit does not do the job as the electricity stands still a short circuit is a circuit that wires have crossed and the electricity takes the shortest path. and does not complete all of the points on the circuit
What does plug key open mean in electric circuit?
When a plug key is open , the circuit is incomplete and is call open circuit.. To be continued..
What is a type of circuit?
a circuit which is open
