Electrical circuits definition

For example [146], a system of interconnected electrical circuits and a mechanical system of masses connected by springs satisfy the same linear equations if system parameters are related by the following definitions ... 

Driven by the energy produced in these reactions, electrons move spontaneously through the external electric circuit containing the load (i.e. a device powered by electric current). According to the definition, the system in the configuration of Figure 3.1.5 operates as a galvanic cell. The Ag electrode is termed the cathode because... 

This chapter has provided basic electrical fundamentals, including concepts and definitions for circuit elements, and their relationships within electric circuits. Various basic AC electric circuits were also presented. Following upon primary circuit theories, the concept of electrochemical impedance spectroscopy and basic information about EIS was introduced. This chapter lays a foundation for readers to expand their study of EIS and its applications in PEM fuel cell research and development. 

An electrical measuring instrument contains electrical circuits incorporating capacitance, inductance, and resistance. In the absence of resistance, a circuit tends to oscillate with a definite frequency /when disturbed. For optimum performance an amount of resistance is incorporated that is barely sufficient to damp the oscillations resulting from transient inputs the circuit is then said to be critically damped. For a critically damped circuit it can be shown that the root-mean-square (rms) fluctuations in voltage V and in current /are given by... 

Spontaneous definition. In the everyday life we come across a graph fairly often, for example, when scrutinizing the map of city streets or highways or railroads, when checking up on an electric circuit, when drawing a technological flow-sheet, and so on. Here is the most elementary definition a graph is a set of points connected by lines. 

The interface Mj M (circuit 1.8) which, in the simplest case, represents a boundary of two metals, is easy to construct. However, the Mi S contact, which includes an additional electrochemical interface, is rarely feasible, being usually unstable and dependent on the nature of Mi. Generally, in place of Mi, a special electrochemical system, the so-called reference electrode should be included into cell 1.8. The electrode potential can be determined as the emf E of a correctly connected electrical circuit formed by the electrified interface under discussion and a reference electrode. According to this definition, the potential of any reference electrode is assumed to be zero.

Wd represents the emitter-coupled oscillator and Cd, and i d are capacitive, inductive, and resistive elements of the equivalent electrical circuit, respectively. Subscript d is related to the particular diameter of the droplet under consideration. (Courtesy of Marcel Dekker, Inc.) Spasic, A.M. Ref. 3., p. 854.
