Not illustrated. 1904 edition. Excerpt: ...discharging. The distortion shows a lag behind the electric stress, a phenomenon known as hysteresis when applied to magnetic induction. The result in both cases is the absorption of energy and the generation of heat. The quantity of heat generated is proportional to the square of the potential difference to which the condenser is subjected. the dielectric is not homogeneous, and that it therefore becomes electrified at the surfaces separating the nonhomogeneous parts, like the electrification of the mica plates. The reunion of these charges is gradual after the first discharge, and their external effect is shown as a residual charge. "According to this theory all charge is the residual effect of the polarization of the dielectric" (Maxwell). In the interior of the dielectric the polarization is neutralized by adjacent opposite charges; "it is only at the surface of the dielectric that the effects of the charge become apparent." 161. Dielectric Polarization (B., 573).--Faraday's theory of induction was that it is an action between contiguous parts of the dielectric, resulting in a certain polarized state of its particles. In proof of this polarization he placed bits of dry silk filaments in turpentine contained in a long rectangular glass vessel with pointed conductors entering from opposite ends. When one of these was connected with the earth and the other with a frictional machine, the bits of silk collected together along lines of induction, forming long filaments of considerable tenacity. Matteucci demonstrated that the dielectric is polarized or charged by contiguous particles throughout. He formed a condenser of a large number of thin plates of mica compressed between two terminal metal plates (Fig. 85). After...
