The equipment used in this work consists of a very stable 2000 watt radio transmitter, an r.f. transformer with tuned secondary, an immersion type specimen cell and a vacuum tube voltmeter. Figure 1 shows the circuit arrangement of these components.
The present method employs the very commonplace phenomenon of timing a parallel combination of inductance and capacitance to resonance. In Fig. 1 a constant voltage E is applied to the L C tuning circuit and C is varied until the current I is a minimum. This residual current is a measure of the total loss of the tank circuit. This loss may be indicated by a figure in mhos conductance, that is the...
