... reminder that capacitance occurs whenever electrical conductors are separated by a dielectric, or insulating, material. This condition implies that electric charge is not transported through ... voltage to the terminals of the capacitor cannot move a charge through the dielectric, it can displace a charge within the dielectric. As the voltage varies with time, the displacement of cha...

... for several reasons. First, the gen- eration, transmission, distribution, and consumption of electric energy occur under essentially sinusoidal steady-state conditions. Second, an understanding ... nonsinusoidal sources. Third, steady-state sinusoidal behavior often simplifies the design of electrical systems. Thus a designer can spell out specifications in terms of a desired steady-...

... resonant filter. A much greater selection of amplifying filters is found among the active filter circuits, the subject of Chapter 15. 14.2 Low-Pass Filters Here, we examine two circuits that ... that divides the passband and the stopband. The definition for cutoff fre- quency widely used by electrical engineers is the frequency for which the transfer function magnitude is decreased by...
