Combination circuit definition

The general shape of this impedance spectrum can then be modeled in terms of an equivalent circuit consisting for example of resistance and capacitance circuit elements combined in definite ways (series or parallel combinations) that can range from relatively simple to rather complex combinations, depending on the degree of complexity of the system under study. This correspondence between an impedance spectrum and an equivalent circuit is well-established in basic physics. These circuit elements reflect various physical features of the real electrochemical system under examination. For instance resistive elements can correspond to interfacial electron transfer processes or represent ionic or... [Pg.166]

An important field of study for power plants is that of the combinedplant [ 1 ]. A broad definition of the combined power plant (Fig. 1.5) is one in which a higher (upper or topping) thermodynamic cycle produces power, but part or all of its heat rejection is used in supplying heat to a lower or bottoming cycle. The upper plant is frequently an open circuit gas turbine while the lower plant is a closed circuit steam turbine together they form a combined cycle gas turbine (CCGT) plant. [Pg.2]

The WE and CE combination represents a driven electrochemical cell. The presence of the RE allows the separation of the applied potential into a controlled portion (between the RE and the WE) and a controlling portion (between the RE and the CE). The voltage between the RE and the CE is changed by the potentio-stat in order the keep the controlled portion at the desired value. Consider the application of a potential Vin to the WE that is more positive than its rest potential, VffiSt, with respect to RE. By definition, polarization of the WE anodically (i.e., in a positive direction) would lead to an anodic current through the WE-solution interface and a release of electrons to the external circuit. These electrons would be transported by the potentiostat to the CE. A reduction reaction would occur at the CE-solution interface facilitated by a more negative potential across it. The circuit would be completed by ionic conduction through the solution. [Pg.32]

In the treatment which follows, we assume that discharge of the doublelayer capacitance drives the reaction, and therefore use C = in Eq. (41). The effects of changes in coverage of the adsorbed intermediate are then taken into account by combining Eq. (41) with the kinetic equations for steps in the mechanism. In this method, no assumptions need then be made about the equivalent circuit or the nature of the pseudocapacitance, and the transient current during potential decay is not assumed to be equal to the steady-state current. The results then enable all three definitions of [Eqs. (46)-(48)] to be evaluated and compared, as illustrated in Fig. 10. [Pg.36]

It should also be made clear that the methods herein described are definitely not the only methods that may be used. In relation to the manipulations possible through a full use of modern electronics, they are crude and basic. Endless variations as well as combinations of these circuits exist. New materials and components are being developed that may find use in this area. Component miniaturization is leading to compact devices. [Pg.285]

He also proposed the circuit symbol shown in Figure 9.29 for the memristor. Looking back, it seems the discovery by Leon Chua did not get as much attention as we today realize it deserved. One reason may be that combining magnetic flux and charge, one could not readily see how this new component could be used in practice. However, using Faraday s law of induction and the definition of electric current in Eq.9.45, it simplifies to ... [Pg.368]

Phasor diagrams and a.c. circuits are an inseparable combination. Phasor diagrams allow us to produce a model or picture of the circuit under consideration which helps us to understand the circuit. A phasor is a straight line, having definite length and direction, which represents to scale the magnitude and direction of a quantity such as a current, voltage or impedance. [Pg.99]

Via the input processor the network, the Bit pattern combinations (test patterns) at the circuit inlet and various definitions for simulation and fault production are fed into the program. [Pg.140]

Like correlation, the mathematical definition of convolution is a combination of two other functions (or sampled data sets). Unlike correlation, g and h are normally very different. As used in signal processing, either gorh represents an input, and the other represents some process, and the convolution of g and h represents the output after the input is processed . The process h could represent the effect of an electrical circuit, and the input g could be the electrical signal as function of time the convolution would be the electrical signal at the output. Or g could be the irradiance from a target, and the process h could be the responsivity of a detector - both as functions of X and y. [Pg.544]
