Polarity (physics) — In physics, polarity is a description of an attribute, typically a binary attribute (one with two values), or a vector (a direction). For example:* An electric charge has a polarity of either positive or negative. * A voltage has a polarity, in… … Wikipedia
integrated circuit — Electronics. a circuit of transistors, resistors, and capacitors constructed on a single semiconductor wafer or chip, in which the components are interconnected to perform a given function. Abbr.: IC Also called microcircuit. [1955 60] * * * ▪… … Universalium
Electrical polarity — (positive and negative) is present in every electrical circuit. Electrons flow from the negative pole to the positive pole. In a direct current (DC) circuit, one pole is always negative, the other pole is always positive and the electrons flow in … Wikipedia
LC circuit — Linear analog electronic filters Network synthesis filters Butterworth filter Chebyshev filter Elliptic (Cauer) filter Bessel filter Gaussian filter Optimum L (Legendre) filter Linkwitz Riley filter … Wikipedia
Bridge circuit — A bridge circuit is a type of electrical circuit in which the current in a conductor splits into two parallel paths and then recombines into a single conductor, thereby enclosing a loop. It was originally used for measurement purposes, but can… … Wikipedia
Track circuit — A track circuit is a simple electrical device used to detect the presence or absence of a train on rail tracks, used to inform signallers and control relevant signals. Principles and operation The basic principle behind the track circuit lies in… … Wikipedia
Track circuit interrupter — A track circuit interrupter may be fitted at catch points, trap points or buffer stops to maintain a track circuit in the occupied state in the event of a derailment. The track circuit remains de energised until the interrupter is replaced.… … Wikipedia
Fixtureless in-circuit test — (FICT) is a cost effective alternative to a bed of nails tester for in circuit testing of low to medium volumes of printed circuit board assemblies. It relies on a computerized optical inspection of the circuit assembly and positionable test… … Wikipedia
LED circuit — In electronics, the basic LED circuit is an electrical circuit used to power a light emitting diode (LED). It consists of up to four components connected in series: a voltage source, a current limiting resistor, an LED, and optionally a switch to … Wikipedia
In-circuit test — (ICT) is an example of white box testing where an electrical probe tests a populated printed circuit board (PCB), checking for shorts, opens, resistance, capacitance, and other basic quantities which will show whether the assembly was correctly… … Wikipedia
Audio mute circuit — Audio circuits need a method to mute the output so that there is no signal at all when desired. One may need to mute when switching programs, at the push of a button, in response to a control signal, when powering up and down, and when the power… … Wikipedia
