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:)

∙ 11y agoIn circuit equivalence, voltage and current sources are respectively equated to short and open ckt because of the very nature of them. A voltage source has zero internal resistance and current source has infinite internal resistance hence their equivalents:-)

Is it possible to do short circuit test of breakers at project site?
Yes, it possible to do a short circuit test of breakers at a project site.
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.
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 the purpose of OC and SC tests on single phase transformer?
Open circuit and short circuit tests are performed to determine transformer characteristics. In the case of a single phase transformer, SC tests would be performed to determine the impedance. The open circuit test will give excitation information (% excitation at specific voltages, often 90%, 100% and 110%, and no load losses).
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.
How will be conduct test on transformer?
Short circuit test and open circuit test are widely used to test the efficiency of the transformer.
Why the open and short ckt test of transformer is needed?
The open/short-circuit test on a transformer isn't 'needed'. It's only used if you want to find out the efficiency of a transformer.
Why do you start with open circuit test?
i hope this may be correct answer but iam not sure this is because if the short circuit test is performed first, because of induction effect some amount of energy is stored in the transformer or motor and while performing the open circuit test there may be a chance of getting error bcz of stored charge as in open circuit test the amount of current is vvv less wnen compared to short ckt by sandeepraj patnala
What is the purpose of open circuit test and short circuit test of a transformer?
An open-circuit test is done with the transformer running at its rated voltage but with no load. This measures the power lost in the magnetic core. (IR Losses) A short-circuit test is done with the transformer running at its full rated current in all windings but at a low voltage. The secondary is shorted and the primary voltage is adjusted to give the rated current. This measures the power lost in the copper windings. (Copper losses)
What is a circuit with no load?
An open circuit or a short-circuit (if that circuit is complete).
What are the types of power transformer test?
open circuit & short circuit test, insulation resistance test, turns ratio, efficiency, if it is oil cooled then breakdown voltage of oil, voltage regulation and definitely visual inpection...
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
Why do you put the meters in the high voltage side in the short circuit test?
in the short circuit test we applied supply voltage on L.V side and short circuit the H.V side and connect the ammeter in H.V circuit to measure the short circuit current. with the help of s.c test we measure the copper losses in the transformers.
Why high voltage is kept open in open circuit and low voltage is shorted in short circuit test?
In Short circuit test High Voltage side is feeded with 2-5% of the High Voltage rating to circulate approximately full load current in low voltage winding by short circuiting it. Low voltage is generally short circuited to facilitate measurements because it is more difficult to measure the quantities at high voltages.
Is it possible to do short circuit test of breakers at project site?
Yes, it possible to do a short circuit test of breakers at a project site.
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.
