Circuits are not made of voltages, they are made of loops. A short circuit exists when a connection is added that is not supposed to be part of the intended circuit as designed. This added connection produces extra loops in the circuit that typically prevent current from reaching parts of the circuit where it is needed and can cause excessive current to flow in other parts of the circuit, resulting in damage to the components in the circuit.
What else can I help you with?
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.
What is the 'short circuit capacity' of a 32A 60898 MCB?
Depends on manufacturer..Normally the ratings are as follows 1. Service short circuit breaking capacity is 7.5 kA 2. Rated short circuit breaking capacity is 10 kA.
What is meant by the term short circuit?
When a wire is cut in a circuit, a gap is made and the current can no longer circulate, known as an open circuit.When 2 parts of a circuit touch, that shouldn't, for example - a wire comes loose and comes into contact with another part of the circuit, its shortening the route of the current in the circuit. So its a short circuit. When this happens 99.9% of the time the result will be a spike in amp's, so tripping any circuit protection, MCB's, fuses.A good example of a common short circuit is faulty windings on a 3-phase electric motor. If the resin separating the windings becomes damaged it can cause 2 or even 3 of the motors phases to come into contact causing the motors overload protection to trip.
What is the resistance of a short circuit in ohms called?
Your original question was in two parts:1.) How many ohms in an open circuit? Infinite ohms (the meter will show no measurement).2.) How many ohms in a short circuit? 0 ohms. There would be no measurable ohms as there would be no resistance in the altered circuit.
How the superposition theorem is used to find the currents in a circuit supply by more than one voltage source?
1.Put a short circuit instead of voltage source 1 and find what you want with taking direction of current in that element(ris.ind.cap.) 2.puta short circuit instead of voltage source 2 and find what you want with taking direction of current in that element(ris.ind.cap.) 3.add current 1 and 2 for any element.
Can you terminate a 110 circuit and a 220 circuit in one box?
No, do not put terminate 2 different voltages in one box.
When you will get to know that short circuit will happen?
1. That if a short circuit occurs we will get a sign before short circuit will happen or not ? 2. what we can do ? 3. how fuse can get a short circuit ? 4. which wires we have to use from preventing short circuit ?

What is a Winding Short Circuit?
When 2 turns of an inductor or transformer short together.
What are the release dates for The Nostalgia Critic - 2007 Short Circuit 1 and 2 2-21?

What would cause a 15 fuse in slot 2 to blow all the time?
A direct short to ground or an overloaded circuit.
What is the analogy of short circuit?
Im searching for the analogies of the following words 1.Overloading 2.Short circuit 3.Circuit Protectors 4.Electromagnetic Induction 5.Len'z law

Why has johny 5 from Short Circuit and Short Circuit 2 changed his name to Walle in his latest film?
Though they look the same tis not the same robot.
What 2 wattmetar indicates for short circuit test?
There are four watt-meters that indicates short circuit test. The four are method, procedure, calculations and fault.
When might it be necessary to use a 2 µF polyester capacitor rather than a 2 µF electrolytic capacitor?
when high voltages are present because the voltage rating of polyester (polyethylene terephthalate) capacitor is high as well as electrolytic capacitor will destroy if the voltage increases from nominal voltage and cause short circuit conditions.
What is Opto-Coupler IC'S?
to prevent the high voltages The main purpose of an opto-isolator is "to prevent high voltages or rapidly changing voltages on one side of the circuit from damaging components or distorting transmissions on the other side."[2] Commercially available opto-isolators withstand input-to-output voltages up to 10 kV[3] and voltage transients with speeds up to 10 kV/μs.[4]
