A radio-frequency capacitance and conductance bridge
R.F. Proctor, E.G. James · The journal of the Institution of Electrical Engineers. Part 3, Radio and communication engineering · 1945
A bridge suitable for the measurement of partial capacitances and conductances is described. It operates at a frequency of 1 Mc/s and is suitable for capacitances from about 0 to 28 μμF and parallel conductances from 0 to 11 micromhos (90000 ohms). The theory of the bridge and the method of calibration of the variable conductance are given. The design of the bridge lends itself to operation at much higher frequencies than 1 Mc/s.
