Irreversibility of current-voltage characteristics in hydrocarbon liquids

الملخص EN

The I-V characteristics curves in this work have been seen irreversible , in purified saturated hydrocarbon liquids, in other words, the conduction Current curves in increasing direction does not coincide with that of decreasing one .

Such behaviour may be attributed to the effect of space charges.

It is also believed that the build up of the space charges is quicker during the increasing direction than its distraction direction in recombination processes, or due to creation of gas bubbles and liquid clusters which leads definitely to complex changes in refractive index and dielectric constant of the tested liquid.
