A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an electric current limited only by the Thévenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion.
A resistor removed from a high voltage tube circuit shows damage from voltaic arcing on the resistive metal oxide layer. Resistors can fail open or short, alongside their value changing under environmental conditions and outside performance limits. Examples of resistor failures include: Manufacturing defects causing intermittent problems.
A different form of short-circuit testing is done to assess the mechanical strength of the transformer windings, and their ability to withstand the high forces produced if an energized transformer experiences a short-circuit fault. Currents during such events can be several times the normal rated current.
Conditional short-circuit current is the value of the alternating current component of a prospective current, which a switch without integral short-circuit protection, but protected by a suitable short circuit protective device (SCPD) in series, can withstand for the operating time of the current under specified test conditions.
A video decoder is an electronic circuit, often contained within a single integrated circuit chip, that converts base-band analog video signals to digital video. [1] Video decoders commonly allow programmable control over video characteristics such as hue , contrast , and saturation .
The article refers briefly to "open circuit" as the opposite of a short circuit. Someone might elaborate on that, perhaps in a separate article. Most commercial power circuitry today provides a fixed voltage, and a short circuit causes the system to attempt to supply unsafe amounts of current to maintain a constant voltage.
Short circuit ratio (or SCR) has multiple meanings: Short circuit ratio (synchronous generator) , a value used to characterize the stability of an electromechanical generator Short circuit ratio (electrical grid) , a metric to characterize the grid strength ("stiffness").
Short Circuit is based on the film of the same name, in which a weaponized robot, Number 5, is struck by lightning and gains human emotion.The president of Number 5's manufacturing company - NOVA Robotics wants to capture him before he can do any harm to the public, and the scientist who built Number 5 wants to disassemble him and discover how he gained emotion.
