capacitor itself draws a charging current from the supply and charges up to a value equal to the applied voltage. Likewise, when the supply voltage is reduced the charge stored in the capacitor also reduces and the capacitor discharges. In an AC circuit in which the applied voltage signal is continually changing from a positive to a negative polarity at a rate determined by the frequency of the supply, as in the case of a sine wave voltage, for example. The capacitor is either being charged or discharged

states that the R in this relation is constant, independent of the current.[3] The law was named after the German physicist Georg Ohm, who, in a treatise published in 1827, described measurements of applied voltage and current through simple electrical circuits containing various lengths of wire. He presented a slightly more complex equation than the one above (see History section below) to explain his experimental results. The above equation is the modern form of Ohm's law. In physics, the term Ohm's

Four types of Noise: Cross talk: Occurs when one circuit picks up signal in another. Occurs between pairs of wires that are carrying separate signals, in multiplexed links carrying many discrete signals, or in microwave links where an antenna picks a wave from another antenna: Echoes: Caused by

. Unit 3 Kaplan University IT530 Professor Jeffrey Robinson August 20, 2013 Abstract In this discussion we look at some of the history around frame-relay. We then look at some of the equipment necessary to create the frame relay connections, as well as how the connections work both logically and physically. Some limiting factors are discussed as well as committed information rates, burst rates, an error handling. Some of the positive aspects of frame-relay

otherwise handle air in a building. Plenum-grade cable can be run through these spaces if local building codes permit it. Decibel (dB) A standard unit used to express a relative measurement of signal strength or to express gain or loss in optical or electrical power. A unit of measure of signal strength, usually the relation between a received signal and a standard signal source. The decibel scale is a logarithmic scale, expressed as the logarithmic ratio of the strength of a received signal to the strength

Airplane electrical systems are important because they run all the stuff that warns the pilots that they maybe stalling out or if something is wrong with the airplane. Electrical systems are powered by two different powers and they are known as direct current and alternating current. The alternating current is the easiest one to produce that it is produce direct current. An alternating current generator utilizes a bundle wire that spins in a field of magnetism, and this field is created by invisible

hardware and basic software that links the machines on a computer network. Computer architecture refers to an entire structure and to the details needed to make it functional. Thus, computer architecture covers computer systems, microprocessors, circuits, and system programs. Typically the term does not refer to application programs, such as spreadsheets or word processing, which are required to perform a task but not to make the system run. In designing a computer system, architects consider
