| Abstract: | Conclusions In adjustable voltage dividers the resistance of the jumpers and the insulation resistance between the contacts of the switches in the jumper circuits cause a positive systematic error of the division factor.The effect of the resistance of the jumpers increases as the resistance of the sections of the transformed portion of the voltage divider decreases, which is one of the causes which limit the reduction of the voltage-divider resistance. The effect of the insulation resistance between switch contacts in the jumper circuits increases as the resistance of the sections of the transformed part of the voltage divider increases. This latter factor is one of the causes limiting the increase in the resistance of the voltage divider.These conclusions apply equally to measurement of a ratio of resistances under conditions in which the method of series-parallel transformation is used.Translated from Izmeritel'naya Tekhnika, No. 6, pp. 62–63, June, 1971. |
