A new configuration for the sample cell to be used in broadband dielectric spectroscopy is presented. A coaxial structure with a parallel plate capacitor (outward parallel plate cell: OPPC) has made it possible to extend the frequency range significantly in comparison with the frequency range of the conventional configuration. In the proposed configuration, stray inductance is significantly dec...

This paper gives a description of measurement technique which can be used in practice carrying out estimation electrical capacitance tested object with substantial stray inductance. Electrical is determined as ratio mean value discharge current to the time derivative, taken from voltage on unknown capacitance. The decreasing deleterious impact inductance accuracy measurements achieved by proper...

When recording intracellularly, the resistance across the cell membrane must be monitored. However the resistance seen by the recording ampli"er consists of the access resistance (between the electrode and the cell) in series with the cell resistance. When the stray capacitance is low, the time constant of the cell and that associated with the recording setup are di!erent and the two resistance...

Nine sets of laboratory exercises are designed to acquaint the student with many aspects of NMR/MRI probe resonant circuits. These include demonstrations of stray inductance and capacitance, matching a resonant circuit to 50 V, inductive coupling, doubly resonant circuits, loading effects of tissue, and radiation from the probe circuit. Many of the exercises are for the bench, but some are perf...

Capacitive electrodes overcome electrode polarization problems and enable noninvasive measurements hence they do not obstruct flow and avoid corrosion, wearing and soiling. However, their impedance is much higher than that of direct contact electrodes and, to reduce it, the measurement frequency must be increased, which worsens the effects of stray interelectrode impedance. In this paper, we an...
