B. is thus-to main-tain a constant and relatively high potential in the in-ductors of the fixed plate. The inductors in turn act upon the combs of the dis-charging conductors, the + inductor attracting the — Eof the comb opposite it and repelling its + E to the endK, and the — inductor attracting the -I- E of the othercomb and repelling the — E. to the end K. The twoends K and K are thus oppositely charged, and whenplaced at the right distance apart a succession of sparkswill pass between them with a snapping sound. Theillustration of the machine shows in addition a jar at-tached to each discharging conductor, called a condenserwhose action is to decrease the number and increase theintensity of the sparks passing between K and K. The Condenser of the Leyden Jar.— A condenser consists oftwo conducting surfaces separated by a dielectric. Oneof the most common forms is the Leyden Jar. (Fig 87.)This
