Description

саторах 2 устанавливаютс  такие напр жени , что зар ды, нротекающие через них в различные Полупериоды, равны по величине и противоположны по знаку. Посто нные составл ющие напр жений на каждом из конденсаторов 2, выдел емые фильтрами 6 и поступающие на клеммы 7, пропорциональны разности проводимости измерительного плеча 4 с измер емым двухполюсником 5 и проводимости соответствующего эталонного плеча 1.The stresses 2 are set to such voltage that the charges flowing through them into different half-periods are equal in magnitude and opposite in sign. The constant components of the voltages on each of the capacitors 2, separated by the filters 6 and fed to the terminals 7, are proportional to the difference in conductivity of the measuring arm 4 with the measured two-terminal 5 and the conductivity of the corresponding reference arm 1.
