In a dielectric liquid with high applied voltages, the current-voltage relationship is known only in two extreme cases: emission-limited injection and space-charge-limited injection. In an actual case, such as in the electrofluiddynamic generator, neither situation is true. In this paper, a more generalized theory of which the extreme cases lead to the above limiting cases is developed. Comparison with the experimental results of Tobazéon showed good agreement.

Electric field distributions have been measured in nitrobenzene using the Kerr electro-optical effect. Both metal and composite electrodes have been used to investigate their charge-injection properties. From the field-distribution measurements it has been shown that positive injection readily occurs when two metal electrodes are used with a space charge near the cathode. When two dissimilar electrodes are used (composite and metal), injection from the composite electrode is always suppressed in comparison with the injection from the metal electrode, this phenomenon being independent of polarity. From the space-charge thickness, estimates of mobility are 1·33 cm2v−1s−1 for the positive carriers and 0·28 cm2v−1s−1 for the negative carriers.
