	Electrical Circuit Breakers (Site not responding. Last check: 2007-10-19)
		In summation, circuit breakers may be called upon to open or close a circuit within a range of from no current flow to as much as fifteen (15) times or more its rated current.
		Circuit breakers are routinely sized to limit thermal energy related damage to the electrical insulation material and not the copper wire.
		Circuit breakers typically will respond to a short to ground that is of the low impedance type as current levels are typically multiples of load currents to which the circuit breaker has been manufactured to sense and then respond to.

	TRANSFORMER EQUIVALENT CIRCUIT
		In electrical engineering, it is often useful to use an equivalent circuit model to describe the non-ideal operation of a device such as a transformer.
		As an example of the usefulness of the non-ideal equivalent circuit, the parameters found in the lab are used to calculate one important transformer characteristic, maximum efficiency.
		With the secondary open, the primary voltage was increased from zero to rated voltage, where the rated voltage is the name plate stamp.

	Open circuit
		A circuit is said to be OPEN when a break exists in a complete conducting pathway.
		Although an open occurs when a switch is used to deenergize a circuit, an open may also develop accidentally.
		To restore a circuit to proper operation, the open must be located, its cause determined, and repairs made.

		The breadth and thickness of the strip and the thickness of the paraffined paper are adjusted so that the relative resistance and capacity of this arrangement are the same as those of the cable with which it is intended to be used.
		One circuit is formed by the loop itself, and a second, quite independent, by the two wires in parallel, earthed at each end.
		After a very short interval of time, the length of which depends on the inductive retardation of the cable, the condensers corresponding to C, and Cs at the other end begin to be charged from the cable, and since the charge of Cs passes through the receiving instrument I or G the signal is recorded.

	Electrical Circuit Breakers
		Breakers are tested in open air, with a temperature of some 40 or 50 degrees C. When a breaker is placed within an enclosure, cooling airflow is restricted; this reduces the ability of the breaker to carry a current to 80% of its ampere rating.
		Circuit breakers are tested and then rated as to their ability to open the protected circuit with a specific amount of current flowing in the circuit.
		A circuit breaker listed to UL standard 489 will open the circuit under fault current conditions and is tested to a higher degree to do so than is a supplementary protector (commonly tested to UL-1077 safety standards).

	Open (Site not responding. Last check: 2007-10-19)
		Open class words belong to a list of morphemes which can be added to by absorbing new words, such as technical terms, slang, as well as adoptions and adaptations of foreign words.
		(Specifically: the union of open sets is open, the finite intersection of open sets is open, and in particular the empty set and X itself are open.) Such a family T of subsets is called a topology on X, and the members of the family are called the open sets of the topological space (X,T).
		Open source advocates point out that as of the early 2000s, at least 90 percent of computer programmers are employed not to produce software for direct sale, but rather to design and customize software for other purposes, such as in-house applications.

	Norton's Theorem
		The value of r is the same as that in the Thevenin equivalent and the current i can be found by dividing the open circuit voltage by r.
		The value i for the current used in Norton's Theorem is found by determining the open circuit voltage at the terminals AB and dividing it by the Norton resistance r.
		In this example, the Norton current is obtained from the open circuit voltage (the Thevenin voltage) divided by the resistance r.

	Explanation of Open and Closed Circuit VWT's

	Open Design Circuits
		The open design community is an established movement now with a large number of designers (home-based, in universities and industry), and becomes a major source for quality designs and new developments.
		Open-design circuits are used routinely as the basis of full-custom chips (thereby achieving top performance for open-design circuits).
		However, we should also consider openness (documentation), and that we may be setting standards for expansion connectors (expect designs for add-on hardware to pop into existence).

	open circuit, closed circuit
		For example, a circuit connected to a dead battery may not perform any work, but it is still a closed circuit.
		A circuit is considered to be closed when electricity flows from an energy source to the desired endpoint of the circuit.
		The open status of the circuit doesn't depend on how it became unclosed, so circuits which are manually disconnected and circuits which have blown fuses, faulty wiring or missing components are all considered open circuits.

	Open-Collector/Open Drain FAQ (Site not responding. Last check: 2007-10-19)
		Open-collector/open-drain is a circuit technique which allows multiple devices to communicate bi-directionally on a single wire.
		Open-collector/open-drain devices sink (flow) current in their low voltage active (logic 0) state, or are high impedance (no current flows) in their high voltage non-active (logic 1) state.
		Although the output of a open-collecter/open-drain device may be in the non-active (high) state, the wire attached to the device may be in the active (low) state, due to activity of another device attached to the wire.

	Open circuit measurement. (Site not responding. Last check: 2007-10-19)
		The measurement used to monitor cathodic protection has been described as an 'open circuit measurement', presumably because one of the poles of the voltmeter is connected to a position in an electrolyte where currents can flow in an open, or unrestricted direction.
		Currents resulting from electrical sources outside of the cathodic protection circuits can effect the meter reading in open circuit measuring.
		Very exact conditions are arranged when a reference electrode is used in the laboratory, so that the measuring circuit is not subject to interference and no indefinable variables are included in the value.
