Abstract
The resistance and power factor of glass condensers were measured at radio-frequencies of 76 to 8250 kilocycles. The resistance-frequency curves show small maxima between 1300 and 1900 kilocycles, and the power factor-frequency curves have an irregular flat region at the same frequencies. The power factor decreases from 60 to 70 per cent. in the frequency range. The resistance was found to vary inversely as the frequency and inversely as the capacity. The greater portion of the resistance of glass condensers as well as of air condensers is due to dielectric losses. In the case of glass condensers a portion of the dielectric absorption is due to polar orientation as explained by the Debye theory.Keywords
