MECHANICAL ANALOGS — III. BY G. E. SCHUCK (A comparative summary of the mechanical and elec-trical relationships analyzed in the article appearingin the last issue is given here in the third paper ofthe Mechanical Analogs series. The author is a mem-ber of the electrical engineering department of theUniversity of Washington.—The Editor.) An examination of Figs. 1 and 3 together withthe curves representing pressure, electromotiveforce, fluid flow and flow of electricity which may be. Fig. 3 found in the previous article appearing in the Sep-tember 1st issue of Journal of Electricity, will leadto the following conclusions. 1. A condenser connected across the mains ofan alternating current circuit acts as an absorbingor elastic medium, a charge of electricity being ab-sorbed by the dielectric during one part of the cycleand returned to the circuit during the other part of The West now purchases $30 worth of electrical appliancesper capita as compared with $7 in the rest of the development means general development and aneven higher purchasing power.
