  Short circuit - Wikipedia, the free encyclopedia
A short circuit (sometimes abbreviated to short or s/c) is an accidental low-resistance connection between two nodes of an electrical circuit that are meant to be at different voltages.
Although usually the result of a fault, there are cases where short circuits are caused intentionally, for example, for the purpose of voltage-sensing crowbar circuit protectors.
In mains circuits, short circuits are most likely to occur between two phases, between a phase and neutral or between a phase and earth (ground).

 DVD Review - Short Circuit   (Site not responding. Last check: 2007-10-21)
With "Short Circuit", Image Entertainment brings us a special edition DVD that is jam-packed with goodies, as well as a good transfer.
The first of the many special features on the "Short Circuit" DVD is an audio commentary featuring director John Badham and screenwriters S.S. Wilson and Brent Maddock.
"Short Circuit" may appear dated in the technology department, but the story still works and the movie is full of laughs and excitement.

 AETCO Short Circuit & Coordination Study
In the Short Circuit Study, the points at which faults are assumed are located on the source side of the device which will be called upon to interrupt the power system when an actual fault occurs.
The Short Circuit Study gives us the information necessary to determine if our breakers and fuses are capable of interrupting a fault, as well as the means of determining whether or not the bus sections of the switchgear are supported adequately to withstand the forces generated from the fault currents.
In addition to the Short Circuit and Coordination Studies, a Load Study should be made on an electrical distribution system to determine the adequacy of the system, as well as the proper sizing and setting of electrical protective devices.

 Short-Circuit Calculation Methods
In addition, a 3-phase short circuit can be considered a balanced load, which means you can use a single-phase circuit to analyze one of the phases and the neutral.
Both methods assume that the fault impedance is zero (bolted short circuit) and the pre-fault voltage is constant during the evolution of the fault.
Thevenin impedance is defined as the impedance seen at any point in a circuit once all the voltage generators have been short circuited and all the current generators have been opened.

Based on Table 4-1, Chapter 4 of the 1993 IEEE Red Book, the unadjusted per-unit reactance of the turbine-generator for both the first-cycle and interrupting networks is 1.0 [X.sub.d]", where [X.sub.d]" is the saturated direct-axis subtransient reactance of the generator in per-unit.

 DVD Verdict Review - Short Circuit 2
Director John Badham's Short Circuit was a surprise box office hit and made audiences fall in love with a pile of nuts and bolts named "Number Five." The semi-good news is that in 1988 a sequel was produced, the cleverly titled Short Circuit 2.
Short Circuit 2 is presented in 1.85:1 anamorphic widescreen on side A and a full frame version on side B. This is a very nice transfer with only a few slight problems showing up.
Short Circuit 2 includes only a couple of special features, including a "Making of Featurette: Actor Profile on Fisher Stevens." This looks as if it were used for promotional purposes back in 1988 when the film was released in theaters.

 The Art of the Creative Short Circuit
The creative short circuit, or the technique that I call circuit bending, is a form of hardware hacking or modding, but with two important differences.
In this way, circuit bending has turned the electronic circuit into an immediate “canvas”; a circuit is accessible at that moment to everyone for the creative act.
A resistor lead within a circuit that is hard to get to, for example, might connect with a printed circuit trace that emerges, with full access, on the other side of the board.

 Exploratorium: Science Snacks: Short Circuit
Thus, most of the resistance of the circuit is in the iron wire.
A short circuit occurs when the current finds a way to bypass the appliance on a path that has little or no resistance - for example, where frayed insulation bares a wire and allows it to touch the frame of the appliance, so the current can flow straight to ground.
If a short circuit occurs - or even if too many appliances get hooked up to one wire, so that too much current flows - the wire in the fuse heats up quickly and melts, breaking the circuit and preventing a fire from breaking out.

 Short circuit
A short circuit is an accidental path of low resistance which passes an abnormally high amount of current.
A short circuit exists whenever the resistance of a circuit or the resistance of a part of a circuit drops in value to almost zero ohms.
Electrons flow through the short (a path of almost zero resistance) and the remainder of the circuit by passing through the 10-ohm resistor and the battery.

 SHORT CIRCUIT CALCULATIONS
Thus to determine the circuit breaker and relay operating times, fault currents and voltages have to be calculated and for many other applications.
When a sudden short circuit occurs on the electric supply system, the currents and voltages are of transient nature before they settle down to steady state values.
For the interruption current rating of a circuit breaker (time involved being 2-5 cycles), the subtransient current is important.

 Short circuit - FIRSTwiki
A short-circuit (sometimes refered to as just a short) is the term used to describe the phenomena when an electric circuit bypasses its main load, taking a shorter and unintended path.
This results in an increased current flowing through the 'short', which can result in excessive heat and fire, destruction of electrical components, and/or releases of toxic fumes.
Damage from electrical short circuits can be prevented or reduced by installing fuses or circuit breakers.
