Unformatted text preview: p and length f. This model allows us to compute forces of electrical origin for systems involving permanent magnets on the same basis as those excited by currents through electrical terminal pairs. 2.1.2 Generalized Capacitance To derive the terminal characteristics of lumpedparameter electric field systems we start with the quasistatic equations given in Table 1.2. The equations we need are (1.1.24) to (1.1.26) and (1.1.13): E  dl = 0, (1.1.24) SD.nda = p, dV, (1.1.25) D = eE + P, (1.1.13) fJ n da = p, dV. (1.1.26) We can use the differential forms of these equations alternatively, although the integral forms are more appropriate for the formalism of this section. It is essential to recognize that an ideal, lossless electric field system consists of a set of equipotential bodies with no conducting paths between them.
