In oil or other liquid dielectrics there are seemingly no such losses as in gaseous media.
If the electromotive force is increased, in the case of a large number of ordinary dielectrics the apparent resistance at the end of one minute's electrification decreases as the electromotive force increases.
Kerr also discovered that when certain homogeneous dielectrics were submitted to electric strain, they became birefringent (Phil.
As an example of the use of Lecher's arrangement, we may quote Drude's application of the method to find the specific induction capacity of dielectrics under electric oscillations of varying frequency.
It was in this way that Drude investigated the specific inductive capacity with varying frequency, and found a falling off in the specific inductive capacity with increase of frequency when the dielectrics contained the radicle OH.
Usually this quality of dielectrics is measured in terms of the same quality in dry air, this being taken as unity.
Of all dielectrics mica is the most suitable for condensers, since it has very high insulation resistance and also high specific inductive capacity, and furthermore may be obtained in very thin sheets.
For further information on the qualities ofdielectrics the reader is referred to the following sources:--J.
It has been shown that this behaviour of dielectrics can be imitated by a mechanical model consisting of a series of perforated pistons placed in a tube of oil with spiral springs between each piston.
It is perhaps to the existence of some such differences as these that we may attribute the specific actions of the different dielectrics in relation to discharge(1394.
The same feeling has led me to make many experiments on the introduction of insulating dielectrics having different inductive capacities (1270.
Probably the effects which have been called effects of unipolarity, and the peculiar differences of the positive and negative surface when discharging into air, gases, or other dielectrics (1480.
An important assisting experimental argument may here be adduced, derived from the difference of specific inductive capacity of different dielectrics (1269.
All seem to me to be dielectrics acting alike, and under the same common laws.
Nothing is perhaps more striking in that class of dielectrics which we call electrolytes, than the extraordinary and almost complete suspension of their peculiar mode of effecting discharge when they are rendered solid (380, &c.
Will the relation of C and B to A be unaltered, notwithstanding the difference of the dielectricsinterposed between them?
It is even possible, that with different electrolytes or dielectrics the ratio may be considerably varied, or in some cases even inverted.
When we pass from the consideration of dielectrics like the gases to that of bodies having the liquid and solid condition, then our reasonings in the present state of the subject assume much more of the character of mere supposition.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "dielectrics" in a variety of sentences. We hope that you will now be able to make sentences using this word.
