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.

∙ 13y agoIn an open circuit, no current flows since there is no path to the load and ground. In a short circuit the supply voltage is directly connected to ground.

When inductor is called short circuit and open circuit?
In DC inductor is short circuited .
What is short circuit ratio of an alternator?
Short circuit ratio is the ratio of field current required for the rated voltage at open circuit to the field current required for the rated armature current at short circuit
When the current will be short and open circuited?
Open circuit has no current, so does that mean any resistor in series with it, has no current ,so it can be ignored for analysis( v=ir so 0 current means 0 V) for finding lets say the Thevenin equivalent.? Now for Short circuit, do we ignore a resistor in series with the short, because current will take path of least resistance and ignore that resistor? Also can short circuit have voltage through it ?
What is two or more electrical components connected together called?
Two or more electrical components connected together is called a circuit. Depending on how components are connected, it is either an open circuit, closed circuit, or a short 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.
What is a circuit with no load?
An open circuit or a short-circuit (if that circuit is complete).
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
When inductor is called short circuit and open circuit?
In DC inductor is short circuited .
What is more dangerous a short circuit or an open circuit?
Open circuit Because, if there's an open, there could be machinery still running, or voltage still present. Short shuts a cct down.
What is the design value of short circuit ration of generator?
short circuit ratio is the ratio of field current to open short circuit voltage n the open circuit current. its value for thermal is less than hydro type.
Open circuit and short circuit test?
Open circuit means the circuit is not continuous . A short circuit is continuous but has a fault connecting between either live to neutral or earth .As result of this we saw that this answer is unsufficent to explain short and open circuit on the other hand you can use this answer also like i did:)
What is short circuit ratio of an alternator?
Short circuit ratio is the ratio of field current required for the rated voltage at open circuit to the field current required for the rated armature current at short circuit
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.
If a fuse melts does it create an open circuit a closed circuit or a short circuit?
If a fuse melts, it creates an OPEN circuit, meaning that no current flows in the wires because it is no longer a complete circuit.
An open circuit results when a hot wire touches ground?
A short circuit is the term for hot touching ground. This can cause a breaker to trip which will then open the circuit.
What is infinity on a multimeter?
If is being used as an ohmmeter it usually means an open circuit. A switch may be open, or a wire is broken (not a short circuit)
What is short circuit ratio?
Ratio of field current required to produce rated voltage in open circuit to the field current required to produce rated current in short circuit.
