Electric circuit model, charge-flow

Modelling plasma chemical systems is a complex task, because these system are far from thennodynamical equilibrium. A complete model includes the external electric circuit, the various physical volume and surface reactions, the space charges and the internal electric fields, the electron kinetics, the homogeneous chemical reactions in the plasma volume as well as the heterogeneous reactions at the walls or electrodes. These reactions are initiated primarily by the electrons. In most cases, plasma chemical reactors work with a flowing gas so that the flow conditions, laminar or turbulent, must be taken into account. As discussed before, the electron gas is not in thennodynamic equilibrium... 

Electrical measurement has three primary aspects the definition of units to describe the electrical properties being measured the modeling, design, and construction of instrumentation by which those units may be applied in the measurement process and the use of measurement data to analyze the functioning of electric circuits. The measurement of any electrical property depends on the flow of electric current through a circuit. A circuit can exist under any conditions that permit the movement of electric charge, normally as electrons, from one point to another. In a controlled or constructed circuit, electrons move only in specific paths, and their movement serves useful functions. 

The most widely used arterial load is the three-element modified windkessel shown in Figure 17.4 [40]. The model appears as an electrical circuit due to its origin prior to the advent of the digital computer. A pressure-voltage analogy was used, with flow depicted by current and volume by charge. Zq is...
